Their ads are loaded with false statements. There are ZERO discounts for using this app/service. The price you pay is EXACTLY what's shown on the pump. The app even shows you a "discounted" price at the pump: false advertising. You get the "discount" as cash back (up to two days later) added to an account which you can cash out at anytime of your choosing. Also, they state "up to $.25 per gallon". While that's technically true, where I'm located I typically see no more than $.12 per gallon.
