If more businesses participated.
If more businesses participated it would be a solid 5 Star app. Still I have earned free money from places I was already going to buy from. Plus I still get my cash back rewards from my credit cards so it's like getting free money twice. Nothing is free but two discounts for the same sale is great. Since I'm a Veteran and some places honor Veterans with a discount I end up with three discounts there. In some cases though when you use a gas station rewards to reduce the price the Upside cash back may be reduced.
