Abstract: A method of operating a shopping notification system may include electronically recognizing a current presence of a customer at a store to provide recognized customer data. A database of previously purchased items of the customer may be accessed using the recognized customer data to provide frequently purchased items information associated with the customer. A category of items including any item in the frequently purchased items information may be determined to have moved within the store in a time between a previous presence of the customer at the store and the current presence of the customer at the store to provide item relocation information and the item relocation information may be electronically provided to the customer.
