In a system and method for obtaining out of stock inventory at a retail enterprise, stored product codes are associated with one or more store codes and each associated store code is associated with an inventory number. The product codes identify products for sale, the store codes identify stores that normally stock the identified products and each inventory number identifies the number of the products in inventory at each store. In response to a wirelessly received product code, store code and customer code, a processor determines the stored product code that matches the wirelessly received product code, the associated store code that matches the wirelessly received store code and its associated inventory number, and controls a communication circuit to wirelessly transmit a notification message to the mobile communication device that transmitted the codes. The notification message illustratively relates to the availability within the retail enterprise of the identified product.
