The app delivers as promised. I would give it five stars, however, all of the font and icons are too small and difficult to read without holding the phone right up to your face. There's no way to adjust the size of font and icons in the app. This makes it very difficult to use at the most crucial time when trying to find a fuel stop.

REVISED REVIEW: Had some initial issues with the sign up and called customer service for help. Didn't really get any....BUT....Did hear back from them again, as a follow up, and they actually did "make it right". So to sum it up; good service over all, just minor hiccup in the beginning.

Hi there, Joanne and John! We're sorry you feel you missed out or that our support team didn't do right by you. We try to offer the best discounts and that means certain offers will sometimes expire. We do offer a lot of different ways to get amazing discounts on diesel every day and we're always adding new locations to our network.

App works great. I was able to save 20 cents per gallon on two fillups. After the 2 fillups, the discounts reduced to 10 cents a gallon. So I guess they limit you on how often you can use it, but I still saved money.
