I've been using it for a little bit now. So far I've used it 6 times and have about $15 in my account. I only bother with if it's at least 10 cents/gallon back. Had to stop for gas the other night and found the closest station to me using my phone. Pulled in and just thought to check the Upside app. The offer for that station was 23 cents back per gallon. That's the most I've ever had. I'm working from home now, so not driving all that much. If you're driving a good bit, though, you could get some pretty decent money back. It's not a ton of money, but it's free money. Of course, I always check to make sure the amount back per gallon isn't negated by higher priced gas, but around here all the gas stations are pretty much the same price, so that hasn't been an issue.
