     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0035]    The preferred embodiments of the invention will be explained below based on the drawings.  
         [0036]    (Embodiment 1)  
         [0037]    [0037]FIG. 1 is a drawing showing construction for executing the method of selling merchandise of a first embodiment of the invention.  
         [0038]    As shown in FIG. 1, this construction for executing the method of selling merchandise of this first embodiment comprises: the Internet  100 , a merchandise-sales-support means (eyewear-sales-support means)  10  that is managed by the eyewear seller (merchandise seller), and merchandise-purchasing-support means  311 ,  312 , . . . ,  31   n  that are managed by the respective eyewear shops (merchandise shops).  
         [0039]    The merchandise-sales-support means  10  receives bidding data via the Internet  100  from a merchandise-purchasing-support means  311  (hereafter, merchandise-purchasing-support means  311  will be used as a representative) used by a pre-registered eyewear shop for the price of merchandise desired to be purchased.  
         [0040]    When the merchandise seller determines that the desired merchandise sales price received from the merchandise-purchasing-support means  311  is greater than the minimum allowable merchandise sales price that is preset in the merchandise-sales-support means  10 , a merchandise sales contract is made with the eyewear shop.  
         [0041]    Also, in the case of bidding having a time limit within a specified period, the number of times a desired merchandise sales price from the same eyewear shop can be received can be limited, for example, limited to a maximum of two times a month.  
         [0042]    Furthermore, the maximum or minimum amount of purchased merchandise corresponding to the desired merchandise sales price can also be included in the bid. In this case, the merchandise-sales-support means  10  receives this bidding data, and can make a contract with the merchandise shop with these conditions as incidental conditions.  
         [0043]    In the case that the purchase period is set in the merchandise sales contract as an incidental condition, the merchandise seller lends a POS (not shown in the figure), which reads two-dimensional barcodes, to the eyewear shop.  
         [0044]    At the eyewear shop, the inventory of the merchandise is managed during the contract purchase period using this POS. During this purchase period, merchandise inventory data that are stored by the merchandise-purchasing-support means  311  is sent to the merchandise-sales-support means  10 .  
         [0045]    At the merchandise seller, the merchandise-sales-support means  10  receives the merchandise inventory data that are stored by the merchandise-purchasing-support means  311  via the Internet, so it is possible to manage the inventory of that merchandise during the purchase period contracted with the eyewear shop.  
         [0046]    Management of the merchandise inventory by the merchandise seller during the purchase period includes the service of automatically sending merchandise and restocking the inventory when fast selling merchandise at the eyewear shop drops below a preset inventory level.  
         [0047]    [0047]FIG. 2 is a flowchart showing an example of the flow of the method of selling merchandise of this embodiment.  
         [0048]    The merchandise-sales-support means  10  receives bidding data for the desired merchandise price, via the Internet  100 , from the merchandise-purchasing-support means  311  used at the pre-registered eyewear shop (step S 1 ).  
         [0049]    The merchandise-sales-support means  10  determines whether or not the received desired merchandise purchase price is greater than the preset minimum allowable merchandise sales price (step S 2 ).  
         [0050]    In step S 2 , when the desired merchandise purchase price is greater than the minimum allowable merchandise sales price (Yes in the figure), processing is performed for making a sales contract for that merchandise with that eyewear shop (step S 3 ). This process is performed for all of the received bidding data that are greater than minimum allowable merchandise sales price.  
         [0051]    Notification data notifying that a sales contract has been made is sent from the merchandise-sales-support means  10  to the merchandise-purchasing-support means  311  (step S 4 ).  
         [0052]    In step S 2 , when the desired merchandise purchase price is less than the minimum allowable merchandise sales price (No in the figure), a notification is sent from the merchandise-sales-support means  10  to the merchandise-purchasing-support means  311  at the eye wear shop that a sales contract will not be made (step S 11 ).  
         [0053]    In the steps shown in FIG. 2, when determining whether or not the price is greater than the minimum allowable merchandise sales price, it is possible to divide the eyewear shops (merchandise shops) into groups before hand, and to set minimum allowable merchandise sales prices for each of the groups.  
         [0054]    A detailed example of dividing the shops into groups will be explained. The users (merchandise shops) of this bidding system are divided into four types (they can be divided even further). A minimum allowable merchandise sales price is set for each of the respective four groups.  
         [0055]    The first group comprises mainly retail stores or franchises (FC) such as a company or individual that pays an initial charge and deposit. After companies or individuals that have paid an initial charge and deposit have been found, it is also possible to include other merchandise shops in this group if approved separately by the merchandise seller. The merchandise shops that belong to this group are trusted for their business transactions so the minimum allowable merchandise sales price can be set low.  
         [0056]    The second group comprises companies or individuals that only pay an initial fee. A shop is classified into this group when approved by the merchandise seller after providing company data or individual data and paying an initial fee. Since no deposit is paid, the minimum allowable merchandise sales price is set higher than that of group 1.  
         [0057]    The third group comprises companies or individuals that can provide a guarantee of self. Since no initial fee or deposit is paid, the minimum allowable merchandise sales price is set based on business trust and is higher than that of group 2.  
         [0058]    The fourth group comprises general companies or individuals. These are normal companies and individuals. Since no data related to credit is provided, the minimum allowable sales price is set higher than that of group 3.  
         [0059]    Furthermore, by adding corrections to the minimum allowable merchandise sales price automatically or during a specified period, based on factors that affect the price, such as seasonal changes, merchandise shipping destination (country, region), number of orders, seasonal changes, currency exchange rate (foreign products, imported products), delivery date, etc., for each of the merchandise sellers registered in the four divided groups, it is possible to apply the system to foreign merchandise shops. Also, it is possible to make public the minimum allowable merchandise sales price in advance based on supply and demand for the merchandise and pricing.  
         [0060]    Also, the bidding system of the method for selling merchandise of this first embodiment is a system for selling merchandise, however, by replacing the merchandise seller with the merchandise buyer and using the merchandise-sales-support means  10 , this embodiment could also be a bidding system for purchasing. For example, in this bidding system, coupons are handled as merchandise, and the merchandise buyer works to purchase the merchandise at as low of a price as possible. That is, by performing the function of both the merchandise seller and merchandise buyer, the merchandise-sales-support means  10  can be used to sell merchandise at as high a price as possible, or to purchase merchandise as cheaply as possible.  
         [0061]    To be more precise, the merchandise-sales-support means  10  operated by the merchandise buyer receives bidding data of the desired merchandise sales price from the terminal operated by the merchandise seller via a network such as the Internet  100 , and makes a merchandise sales contract to purchase merchandise from a merchandise seller, whose desired merchandise sales price is lower or less than a preset and confidential maximum allowable merchandise purchase price, or from a merchandise seller, whose desired merchandise sales price is the minimum desired sales price.  
         [0062]    The merchandise, which is the target of the bidding, is not limited to eyeglasses and contact lenses, but can be any marketable merchandise or service that can be bid on.  
         [0063]    The method of selling merchandise of this first embodiment is constructed as described above and has the following effects.  
         [0064]    By receiving bidding data related to a desired merchandise purchase price and sales-support service from a plurality of pre-registered eyewear shops via the Internet  100 , it is possible to more efficiently provide support services and set sales prices for each of the eyewear shops of various sizes, while at the same time maintaining profit for both seller and buyer. Also, by not making the bidding prices public, it is possible to prevent a price collapse of the merchandise, and thus it becomes possible to set one-time-only discounts.  
         [0065]    (Embodiment 2)  
         [0066]    [0066]FIG. 3 is a drawing showing construction for executing the method of selling merchandise of a second embodiment.  
         [0067]    As shown in FIG. 3, the construction for executing the method of selling merchandise of this second embodiment comprises: the Internet  100 , a merchandise-sales-support means  10  that is managed by an eyewear seller (merchandise seller), merchandise-manufacture means (eyewear-manufacture means)  201 ,  202 , . . . ,  20   n  that are managed by respective eyewear manufacturers (merchandise manufacturers), and merchandise-sales means (eyewear-sales means)  301 ,  302 , . . . ,  30   n  that are managed by respective eyewear shops (merchandise shops).  
         [0068]    The merchandise-sales-support means  10  receives data from the eyewear-sales means  301  (hereafter, eyewear-sales means  301  will be used as a representative) via the internet  100  related to the user  90  such as measurement results, which include eye-examination data such as vision of the user  90 , and face data that uses 3-dimensional image technology, and conditions of use such as how the eyewear will be used.  
         [0069]    Also, the merchandise-sales support means  10  selects data related to the most suitable eyewear (merchandise) for the user based on the data related to the user  90 , and sends that data via the Internet  100  to the eyewear-manufacture means  201  (hereafter, eyewear-manufacture means  201  will be used as a representative), and gives an instruction to manufacture the eyewear. It can also give instructions of where to deliver the eyewear.  
         [0070]    [0070]FIG. 4 is a drawing showing the construction of the eyewear-sales means  301  in FIG. 3.  
         [0071]    The eyewear-sales means  301  comprises: an eye-examination means  310  for the user  90 , a 3-dimensional-image means  320 , and an interactive type communication means  330  for asking questions such as the conditions for use.  
         [0072]    The communication means  330  can add to and update the contents of the questions stored in its database. For example, in addition to receiving selections corresponding to questions, it receives input such as questions from the user  90 , and gives answers to the questions and advice to the user  90 . The communication means  330  is used for adding these questions, answers and advice and updating the contents of the questions.  
         [0073]    The eyewear-sales means  301  sends data to the merchandise-sales-support means  10  via the Internet  100  related to the user  90 , which includes eye-examination data such as the vision of the user  90  from the eye-examination means  310 , face data from the 3-dimensional-image means  320  and conditions of use such as how the eyewear will be used from the communication means  330 .  
         [0074]    [0074]FIG. 5 is a drawing showing the construction of the merchandise-sales-support means  10  in FIG. 3.  
         [0075]    The merchandise-sales-support means  10  comprises: a memory means  20 , optimum-selection means  30 , question-answer-assistance means  40 , and manufacture-instruction means  50 .  
         [0076]    The memory means  20  stores a database related to eyewear lenses and frames, and a database related to the contents of the questions stored by the communication means  330  shown in FIG. 4.  
         [0077]    The optimum-selection means  30  selects candidates for the most suitable eyewear from the database related to the eyewear registered in the memory means  20 , based on face data and preferences of the user  90 , such as color and design of the eyewear, that are included in the received data related to the user  90 .  
         [0078]    Also, the optimum-selection means  30  combines the face data with the selected eyewear and displays a synthesized image of the eyewear being worn by the user and prompts the user  90  to select the most suitable eyewear.  
         [0079]    The method of selection is performed based on measurement results containing eye-examination data such as vision, conditions of use such as how the eyewear will be used, lens characteristics, and characteristics of the eyewear frames, and is narrowed down by conditions such as lens conditions such as material, specific weight, thickness, for example, lightweight plastic or hard, thick glass, and frame conditions such as material and specific gravity, for example, lightweight, anti-corrosive, and the like.  
         [0080]    When the question-answer-assistance means  40  receives data related to the user  90 , including questions from the user  90  that are entered by the communication means  330 , that data is used for adding to or updating the database related to the question contents stored by the communication means  330  in the memory means  20 . Also, when the technician operating the question-answer-assistance means  40  is capable of answering the questions, the answers and advice are sent in realtime to the communication means  330  and the user  90  is notified.  
         [0081]    The manufacture-instruction means  50  sends the data related to the most suitable eyewear received from the merchandise-sales-support means  10  to the eyewear-manufacture means  201  (hereafter used as a representative eyewear-manufacture means) via the Internet  100 , and instructs that the eyewear be manufactured.  
         [0082]    Moreover, based on the preferences of the user  90  such as lens characteristics, eyewear frame characteristics, color, material, design and the like that are contained in the data related to the most suitable eyewear and that are selected by the user  90 , the manufacture-instruction means  50  selects the most suitable manufacturer from among the eyewear manufacturers that manage the eyewear-manufacture means  201 ,  202 , . . . ,  20   n  that are pre-registered on the server of the Internet  100 , and instructs that the eyewear be manufactured.

         [0084]    Also, it is possible for the manufacture-instruction means  50  to send an instruction to the eyewear manufacturer to deliver the manufactured eyewear to a specified location such as a specified place or specified person.  
         [0085]    Next, another example of using the merchandise-sales-support means  10  shown in FIG. 3 will be explained.  
         [0086]    [0086]FIG. 6 is a flowchart showing an example of the operation of the merchandise-sales-support means  10  shown in FIG. 3.  
         [0087]    In the case that merchandise code, which can specify merchandise on a normal sales network, is set for the merchandise sold to a pre-registered user  90 , and sales price information is received from the user  90  of a second sales price on another pre-registered normal sales network that is lower than the first sales price at the time the merchandise was ordered, the sales price charged to the user  90  is changed from the first sales price to the second sales price.  
         [0088]    The merchandise-sales-support means  10  receives information related to the merchandise code and sales price of the merchandise in question at another shop via the Internet  100  from the user that purchased the merchandise (step S 21 ).  
         [0089]    The merchandise-sales-support means  10  then determines whether or not the sender of the data is a registered user  90  (step S 22 ).  
         [0090]    In step S 22  when the sender is a registered user  90  (Yes in the figure), the merchandise-sales-support means  10  determines whether or not the received merchandise code and other shop are registered (step S 23 ).  
         [0091]    In step S 23 , when the merchandise code and other shop are registered (Yes in the figure), the merchandise-sales support means  10  determines whether the sales price at the other shop (second sales price) is lower then the sales price given to the user  90  (first sales price) (step S 24 ).  
         [0092]    In step S 24 , when the sales price at the other shop is lower (Yes in the figure), price adjustment is performed to replace the price given to the user  90  with the sales price at the other shop (step S 25 ).  
         [0093]    In step S 24 , when the sales price at the other shop is not lower (No in the figure), processing ends.  
         [0094]    In step S 23 , when either the received merchandise code or other sales shop is not registered (No in the figure), processing ends.  
         [0095]    In step S 22 , when the user  90  is not registered (No in the figure), processing ends.  
         [0096]    Also, changing the price from the first sales price to the second sales price is performed when the sales price is greater than (higher than) a preset sales price.  
         [0097]    An invoice is sent to the user  90  according to the changed sales price.  
         [0098]    Furthermore, changing the price from the first sales price to the second sales price is performed within a preset period after the merchandise is ordered.  
         [0099]    In the case that the user  90  has finished paying for the merchandise, it is possible to process a discount for the user  90  equal to the difference in the first sales price and second sales price.  
         [0100]    When a merchandise code is set for the merchandise that was sold to a pre-registered user  90  that makes it possible to specify the merchandise on a normal sales network, and information is received over a network, such as the Internet  100 , from the user  90  that a second sales price for merchandise on another pre-registered normal sales network is lower than a first sales price at the time merchandise was ordered, the sales price is changed from the first sales price given to the user  90  to the second sales price.  
         [0101]    Also, changing the price from the first sales price to the second sales price is performed when the sales price is greater than (higher than) a preset sales price.  
         [0102]    Furthermore, changing the price from the first sales price to the second sales price is performed within a preset period after the merchandise is ordered.  
         [0103]    In the case that the user  90  has finished paying for the merchandise, it is possible to process a discount for the user  90  equal to the difference in the first sales price and second sales price.  
         [0104]    This second embodiment of a method for selling merchandise is constructed as described above, so it has the following effects in addition to the effects of the first embodiment.  
         [0105]    By giving answers to questions from the user  90  and providing advise after receiving data related to the user  90 , which includes eye-examination data such as the vision of the user  90 , face data, and conditions of use such as how the eyewear will be used, it is possible for the user  90  to satisfactorily select the most suitable eyewear.  
         [0106]    By selecting the most suitable eyewear manufacturer from among pre-registered eyewear manufacturers, sending data related to the selected eyewear via the Internet  100  and giving instructions (request) to manufacture the eyewear, it is possible to ask an eyewear manufacturer, which was determined to be the most suitable according to their record, to manufacture the eyewear. It is also possible to do away with space for manufacturing.  
         [0107]    Also, by sending an estimate request, it is possible to provide the most suitable eyewear from the aspect of delivery date and cost to the user  90 .  
         [0108]    The merchandise that is the object of the merchandise-sales means  301  of the method of selling merchandise of this embodiment is not limited to eyewear, and the embodiment can be applied as well to other accessories such as clothing, hats, shoes, rings and the like. There is no need for an in-shop specialist or technician at the sales location where the merchandise-sales means  301  is set up, so use at stores such as convenience stores is also possible.  
         [0109]    It is also evident that a technique of reading barcodes, including QR code, Vericode, 3-dimensional code, or a technique of reading symbols or characters such as OCR can be applied instead of the 2-dimensional barcode used in this embodiment.  
         [0110]    Moreover, the invention is not limited to this embodiment, and can be applied to suitable technology related to this method of selling and merchandise and method of purchasing merchandise.  
         [0111]    Furthermore, the number, location and shape of the above components are not limited by this embodiment, and any number, location or shape that is suitable to the invention is possible. In the drawings, the same code numbers are used for identical elements.  
       INDUSTRIAL APPLICABILITY  
       [0112]    The invention constructed as described above has the following effects.  
         [0113]    By receiving bidding data from a plurality of pre-registered merchandise shops via the Internet related to a desired merchandise purchase price and sales-support services, it is possible to efficiently provide support service and set sales prices for each of the merchandise shops of various sizes, while at the same time maintain profit for both seller and buyer.  
         [0114]    Since prices, such as the desired merchandise purchase price or the minimum allowed merchandise sales price, are not made public, and since a minimum merchandise sales price is set, it is possible to reduce the time required for price negotiations in business transactions. Moreover, with purchase bidding, opportunities for purchasing merchandise cheaply increase.  
         [0115]    By giving answers to questions from the user and providing advise after receiving data related to the user, which includes eye-examination data such as the vision of the user, face data, and conditions of use such as how the eyewear will be used, it is possible for the user to satisfactorily select the most suitable eyewear.  
         [0116]    Also, by using the Internet, it is possible to select an eyewear manufacturer from among a plurality of eyewear manufacturers that is the most suitable from the aspect of technology, cost and delivery date.  
         [0117]    By using POS that utilizes barcode technology, which includes 2-dimensional barcodes, at each of a plurality of shops, it is possible to perform detailed management of inventory merchandise. Also, by monitoring the merchandise inventory data of each shop via the Internet, it is possible to prevent the inventory from running out at each of the shops.  
         [0118]    By receiving a request to correct the sales price of merchandise already purchased and adjusting the sales price when a user finds that the merchandise is being sold more cheaply at another pre-registered shop, it is possible to prevent losing users.  
         [0119]    Since discounts are adjusted when the sale price is greater than (higher than) a preset sales price, it is possible to stop the sales price from becoming too low.  
         [0120]    By adjusting the sales price within a preset period after merchandise has been ordered, it is possible to limit the period for receiving price adjustments.  
         [0121]    In the case that the merchandise has already been paid for, it is possible to adjust the price by refunding money to the user equal to the difference between the first sales price and second sales price.
