The first two fill ups, no problem with cash back. I fill up with gas everyday and have 3 gas reciepts pending and have been for 6 days now. For me, with 3 reciepts pending that I will lose in 4 days, this app isn't reliable, nor worth my time. Once I lose the cash back for $60 worth of gas in 4 days, as 10 days is no longer refundable, this app will be deleted from my phone.
