At first this app was quite useful. But, over the past couple years I have had too many stations not honoring their offers, namely Raceway here in VA. Or, could it also be apps fault... who are not tracking and enforcing dealers to honor their prices? I continually get notices like, "Sorry we're having trouble w/your last transaction. Thanks for being patient we're working on it". But, money never comes, and shows "Expired". Forget this app- and use GasBuddy!
