A system for providing instant rebates to a customer at a point of sale includes a kiosk by which the customer initiates a rebate process by presenting a machine readable document having rebate information generated by a retailer's POS system. The customer may initiate an electronic funds transfer to the customer's account for amount of the rebate due, or alternately receive a printed check or a store card with a credit balance redeemable at the point of sale. The kiosk may report rebates in real time and have additional functionality to assist manufacturers and retailers for other marketing purposes.
