A mobile application (“app”) enabling a shopper to identify an item or items that the user wishes to locate or purchase. The device displays a list of stores which stock the item(s), and a user is then provided with in-store guidance enabling the shopper to find the item or items that the user wishes to locate or purchase. A user can identify an item or items by scanning a product bar code, scanning a product label; capturing an image of a product, or typing a product name in a search field. The method further includes identifying stores that stock the item. Items can be added to an accumulative shopping list, and items may be ordered online if not available nearby. The system provides basic navigation to store(s) carrying the item(s). Once at a store, an interior route to a product is portrayed through an overhead view map of a store layout. Once near a product, a user may be shown a virtual display of a shelf with the vertical or height placement of the product on the nearby shelf.
