Save some cash every time you fill up. I use this app in combination with a 3% cash back credit card. I go to CircleK to fill up, I was given a discount card a couple months ago for 20¢ off a gallon which expires sometime in May, so thats cool they do that and if you go on a Thursday most of the CircleK stations also give 20¢ off a gallon. You are able to stack the discount given by Upside with the discount cards CircleK gives you or on those Thursday deals. We can also save more if you use my invite code Y7Y2P You will get an extra 15¢ a gallon cash back the first time you use the app. Why spend more when you can save!!!
They make money by adding companies to the list of gas stations, restaurants and groceries stores and there could be some ads. They dont have your complete credit card info, only some of it, so thats good.
