Abstract: A computer program product for prioritizing order fulfillment at a retail sales facility, including the steps of: a) receiving purchase request information at a retail sales computing device that includes identifying information and order information for the first customer, b) receiving location information for the first customer, c) processing the received location information for the first customer together with location information of the retail sales facility to predict an estimated time of arrival (ETA) for the first customer at the retail sales facility, d) scheduling a time interval for acquiring updated location information for the first customer, and e) placing the identifying information, order information and ETA for the first customer in an order fulfillment queue for all current customers. Entries in the order fulfillment queue are ordered in increasing ETA order, whereby order fulfillment activities can proceed according to the order of order requests in the order fulfillment queue.
