A navigation system is configured to plot a route through a shopping area that visits various stores offering specific types of promotions. A user of the navigation system first selects a desired promotion, including a discount level, among other possibilities. Then, the user selects a category of store where the user wishes to shop. The navigation system then identifies nearby stores offering the desired promotion that fall within the selected category, and plots a route that visits each identified store. The route may traverse from the current location of the user to a final destination, or may represent a circuit with collocated starting and ending positions. |
