A computer-implemented system comprising a processor for an electronic data exchange using Internet to facilitate request for bids from prospective restaurant customers which become binding upon restaurants when the prospective customer honors, in full, his conditional promises to a restaurant. The processor receives offer from the restaurant's system including a minimum dollar amount, a range of time for which the offer is valid, and a customer discount associated with the offer, which are matched with the received RFB from the consumer's device, the RFB including a geographic location of restaurant, a minimum amount of money to spend and a range of time at which the consumer will promise to honor a deal. The processor searches the restaurant offers database to match one or more restaurant offers with the RFB criteria and serves said identified one or more restaurant offers to the consumer for acceptance.
