This app sucks. In order to link a fuel rewards card you have to enter the card number, pin number, your zip code and last name. However I'm only able to type in the card number line. No matter how many times I click on the lines for pin number, zip code or last name, it won't even register that I clicked on them, so there is no way for me to add this card. The app is also saying I'm too young for tobacco and alcohol rewards? I'm 21.
