I can’t tell you how many times I’ve been driving around town on a Friday and taken advantage of this deal at McDonalds.
Every Friday in the McDonalds app, they offer a $1 large fry coupon. It’s so easy to use - you just open the app, click the offer to redeem, and give the cashier the coupon code on your phone. Your $1 large fry will automatically ring up in their system!
