Oh Thank Heaven for Seven-Eleven Windows Phone 8 app
The UI is similar to the iOS and Android app and includes a store finder and a mapping function to help you find your way to the closest jar of pig's feet and Slim Jim. The app is set up with four different sections including deals good for today only, deals for in-store food, coupons for merchandise in the store and the aforementioned store finder.
The Seven-Eleven app for Windows Phone 8 is a free download from the Windows Phone Store.
