Abstract: A conditional purchase offer (CPO) management system is disclosed for receiving CPOs from one or more customers, such as airline passengers, and for evaluating the received CPOs against a number of CPO rules defined by a plurality of sellers, such as airlines, to determine whether any seller is willing to accept a given CPO. A CPO is a binding offer containing one or more conditions submitted by a customer for purchase of an item, such as airline travel, at a customer-definied price. A CPO rule is a set of restrictions defined by a given seller, such as an airline, to define a combination of restrictions for which the seller is willing to accept a predefined price. The CPO rules may be securely stored by one or more servers. The CPO management system permits a seller to correct for forecasting errors, if necessary, or other competitive forces which have produced excess capacity, by providing inventory for sale to CPO customers.

Abstract: A system and method are disclosed for encouraging buyers to submit CPOs to a CPO management system for a desired product. The CPO management system processes each received CPO to determine whether one or more sellers are willing to accept a given CPO. The disclosed CPO management system compensates buyers if the buyer's conditional purchase offer is rejected, or expires before an acceptance is received. If a CPO is rejected by the sellers, or has expired before an acceptance is received, the CPO management system evaluates one or more stored compensation offers to determine if the buyer is eligible for rejection compensation. The compensation offers may optionally require that the conditional purchase offer satisfies one or more additional predefined eligibility criteria. If the predefined criteria is met, the rejection compensation is provided to the buyer.
