The second part is a listing of specific items of interest grouped in broad categories by type of material. This is followed by a source code that refers to the source for the item. Items With Multiple Sources Many of the items in the catalog are available from various sources, either locally or on the Web. In this case, potential buyers will probably want to check with their favorite vendor of educational materials, other local sources, or even the Internet before making their purchase. Using a local source may allow the buyer to get a closer look at the item or perhaps try it out first.
Some websites even offer demos of computer-related products.
Some Shopping Suggestions Prices can vary widely, particularly with newer media like CD-ROMs, so it pays to shop around for the best deal. Even if you would rather not purchase something through the Web, using it can be valuable. It can provide you with the names of sources in your area that carry the item and who has the best price. You might also find reviews of the item that will help you make your decision. To go shopping on the World Wide Web, just go to your favorite search engine and enter the title of the item.
