Abstract: A computer-implemented system links product information, location and sales information with mobile computing devices such as a smart-phone of a shopper. The shopper's smart-phone displays a route to the products in which she is interested by input to the application on his or her phone or mobile computing device. The shopper is efficiently mapped to the products in the most efficient order, and product and promotional sales information, such as instant coupons, are downloaded to the shopper's phone or device leading to an efficient shopping event without wasted time or missed sales or coupon opportunities.
