The only times I have tried to use an offer in the Wendy's app, they haven't worked. The first time I placed my order and when I tried to use the code it said it wasn't found, I had to pay full price. The second time, I loaded the offer and when I got to the use in restaurant button it looped back to the offer page and then disappeared. What's the use of having offers if they aren't available at the cashier or disappear when you try to redeem them?
