Be careful using the app. Frequently the app will say that you are not at the correct location. Then the next sceen indicates that everything is working correctly. I submit and am denied. I liked the app but it has been inconsistent at best. Yesterday it happened again! Pull in to the station, claim the offer, only to have the app say I'm not at the right place! First page says yes! Second page says no! I think it may be time to give up. It works periodically.
