Abstract: A method of integrating a retailer's E-Commerce and Point of Sale presences is described. A database of shopper profiles is populated by a first server. The shopper profiles correspond to a plurality of shoppers. Each shopper profile corresponds to one or more shoppers accessing the retailer's E-Commerce presence over a first network. A geolocation of a first mobile device having an application that is associated with the retailer is identified. The mobile device is associated with a first shopper from the plurality of shoppers. A second server determines that the first shopper is geographically proximate to a brick and mortar presence associated with the retailer based on the identified geolocation. A promotion for the first customer redeemable while the first customer is at the retailer's brick and mortar presence is selected. A third server transmits the selected promotion to the mobile device of the first customer over a second network.
