Abstract: A shopper assistance system may include a mobile device associated with a shopper, and a shopper assistance server. The server may, as the shopper moves along a path of travel within a physical store, cooperate with the mobile device to obtain geographic position data associated with a shopper position within the physical store, and determine a shopper dwell time at a given shopper position within the physical store based upon the geographic position data. The server may also determine a product for purchase adjacent the shopper based upon the given shopper position and cooperate with the mobile device to provide a user interface for providing shopper assistance with the product for purchase based upon the shopper dwell time. The server may also generate and communicate to the mobile device a digital promotion based upon the shopper dwell time.
