Weirdly, when I was broke and jobless, living off the deals from McDonald's was pretty decent. I could normally get a free fries or sandwich practically every day on the app.
The app gives pretty good discounts. It's pretty easy to save about 20% using the app for an order. I think the rewards is also about 10-15%. If you are going to go to a Quick Stop Restaurant, it's generally a good idea to use the app.
