Systems and methods for conducting e-commerce provide notification to customer about opportunities suited to the customer's specific request and about opportunities in which the customer's request can be aggregated with similar requests of other customers. A features of notifying into the future is provided, in which a customer's request (20) that includes at least a description of a desired purchase is sent and is accepted at a server (10), and then vendors (30) are identified, and then the customer is notified about offerings that match the request (111). The notifications begin at the time the request is originally made, and continue at additional times into the future (113). The steps of identifying vendors and notifying the customer are repeated into the future to catch matches that might not be available the first time a check for matches is made. The repetition can be for a certain period of time, or it can be terminated by a certain event or set of circumstances (114). For example, the notification may end if a time limit is reached, such as the close of an auction. As another example, the nofification may end if there is an indication by the customer that further notification is unnecessary, as when the customer has completed the transaction that was intended.
