Patent ID: 8260685

Claim:
Computer storage media storing computer-executable instructions thereon that, when executed, perform a method of providing time-sensitive information that is usable to determine when to purchase a product, the method comprising: receiving from a client computing device a request to send information that describes products, wherein the request includes a purchase-price parameter usable to identify the products; retrieving from a datastore a first product, wherein the first product satisfies the purchase-price parameter at a time at which the request is received; retrieving from a datastore a second product, which is usable as an alternative to the first product and is available to be purchased at the time the request is received for a second-product price that is greater than the purchase-price parameter; retrieving from the datastore a set of time-sensitive information that is usable to determine when to purchase the second product, which includes the second-product price that is greater than the purchase-price parameter, wherein the time-sensitive information indicates that the second-product price will be changed to a modified purchase price on a future date; comparing by a processor the modified purchase price of the second product to the purchase-price parameter to determine that the modified purchase price will satisfy the purchase-price parameter on the future date; and transmitting information that describes the second product to the client computing device.
