• executing a competitor module, coupled to the offer module, for identifying a competitor's offer near a sale location;
• executing a time module, coupled to the competitor module, for calculating an extra travel time to a competitor's location of the competitor's offer;
• executing a cost module, coupled to the time module, for calculating an extra travel cost to the competitor's location of the competitor's offer;
• and
• executing an alternative module, coupled to the cost module, for generating a competitor notification of the extra travel time and the extra travel cost.
