This app worked Great until I started driving out of my way to other towns to fill up and that when I noticed it throwing out my receipt saying receipt not provided time has expired .so you will NOT receive the cash they offer when you are actually going to MAKE A FEW DOLLARS. IT WILL DISAPPEAR INTO CYBERSPACE. BUT GOOD NEW YOU WILL GET CREDIT WHEN IT'S A COUPLE OF CENTS PER GALLON I'VE EMAILED A FEW X'S & GOT NO RESPONSE!😡 I'VE ALSO MESSAGE FROM APP UNDER CONTACT US & NOREPLY THERE EITHER
