System, program product, and method for comparison shopping with dynamic pricing over a network

摘要

A computer executes a bid agent process that receives one or more selection requests for selected products over one or more of the network interfaces. A bid request process sends a bid request over one or more of the network interfaces to a one or more stores requesting a bid on the selected product. The bid request has a bid protocol agreed on by the stores and the stores also agree to send a bid within a time period. A bid receiving process then receives the bids and resends the bids over the network interface to the user.
