Let me start this post by saying I remember when gas was .99 cents a gallon. That was premium gas, not just regular...regular was like .79 cents a gallon. Yes, I'm that old. Thank goodness for Upside . You actually get money back from this app for your gasoline purchases & other purchases, like restaurants,stores, etc. I don't know what gas is where you are but in Jersey...it's almost $5 a gallon, even with the "tax holidays" the President is giving us. Let's take a look at some of the perks. upside is a free cash back app that users can earn up to 25¢/gallon cash back on gas. Use New "Check In" and skip the receipt. Just Check In to redeem your offer at this station and any other locations that have a Blue Badge. No need to upload receipt. upside uses the last 4 digits of your cards from recent purchases to verify your purchase. Tap the "Check In" button when user is at business and select which card they're using - no receipt pic
