This App sucks. I've had so many instances where I was at the drive thru trying to use the coupon and ended up having to pay regular price because the coupon wouldn't load. If you have an experienced cashier, they may manually apply the coupon but sometimes that's not the case. The other wonky thing that happens is the coupon dissapears if you view the details of the coupon. Don't look at it until you are in front of the cashier or you will lose it even though you didn't use it.
