Abstract: A system and method is provided for delivering in-store product information to customers using a remote server, a network, and one or more end user handheld devices. The method entails providing a network storage device with a product information database stored thereon. The storage device is connected to a network and the database is maintained by an administrator with the latest pricing information, inventory levels, and product location data for in-store products. A loadable application layer on the user handheld devices is provided for end users to access the product information database over the network. Users can query the product information database using the application layer to, among other things: select and view available products available in the store, create shopping lists, view sales, and calculate price totals for products placed on the user's shopping lists. Consumers are therefore afforded real-time product information while shopping or prior to arriving.
