This app is widely advertised as a way to save money on fuel purchases. However this is only true on the first purchase with the initial promo code, which gave me a 10% return. Not bad right? The catch is that you have to go to whichever gas stations they list and after the promotional code is no longer in effect you only save from 1 cent to 6 cents, at places where the prices are some of the highest, at least in my area. I can actually save 5 cents a gallon by not using the app.🤔
