A method for processing a rebate claim. The method comprises providing a web site accessible by the consumer and integrated with a processing system accessible by the retailer. The processing system receives an identifier of a qualified transaction and/or of the consumer, and receives information from which it can be determined if the qualified transaction at least partially satisfies a rebate offer. Information from the consumer is received on the web site sufficient to match identifying information about the consumer to the information from the retailer and/or sufficient to satisfy conditions for making a rebate claim. The rebate claim is validated and the value of the rebate offer is transferred to the consumer. Embodiments are discussed relating to transactions on a computer network, making rebate claims via a wireless communications device, and use by membership clubs or in conjunction with loyalty cards or other designated cards.
