I found this app to be a rip off. The only gas stations that they have are the expensive ones that you can fill up at. They are 30 to 40 cents more expensive than others around. So if you get 15 cents cash back at the expensive stations why not just go to the cheaper ones to save more money rather than getting the cash back? So I'd rather save $7-$8 at the cheaper stations than get $3-$4 cash back just because I went to an approved GetUpside gas station. Seems pointless to me.
