I recently, like around 8 p.m. on Sunday, January 7th, 2018. A BOGO coupon for blizzards. When I presented the coupon to the cashier, it would only show a tab to press for driving directions to the nearest DQ, which in my case, is at 43rd ave and Dunlap. When I went in to order my blizzards and redeem the coupon, the app, said my coupon had already been redeemed. Anyone else have this experience with the dairy queen app?
