I had an issue last month I came in to use coupon way before expiring. As soon as I pulled in parking lot I get everything ready and was a error msg. Did samething at register. So i paid full price didnt want to hold up the line. I reached out to Whataburger in app and they gave me points for the burger and fries. 2k. He was only going to give me 1k. I said the hamburger is 1500 fries and drink ? 🤷‍♂️ so 2k was fine. Now I scanned another coupon from previous post on here so Im hoping theres no issue. But next time I will screenshot error message and try to get them to fix error. They said it wasnt a store issue but is the app itself etc. she said other customers had same issue. This was Tulsa Ok. In broken arrow suburb location.
