A retail shopping facility having at least one public entrance, a customer service area, a product display area, and at least one point-of-sale (POS) station also has at least one scanner configured to remotely and uniquely identify a product previously purchased from the product display area as that product re-enters the retail shopping facility via the public entrance with a customer. That scanner provides corresponding identifying information regarding that returning product to a control circuit that in turn uses that information to automatically process an exchange transaction of the returning product for a substitute product in the product display area such that the exchange transaction occurs without the customer engaging either the customer service area or one of the POS stations.
