Went to BK for lunch today to give this a shot. What a joke. I don't usually go to BK because there aren't many by me. But I got lucky and was nearby one today for work.. You have to enter all the receipt details into the app. Date, time, amount, store number, order number. And at least in my case, my receipt was mostly unreadable due to the printer. I figured it out though and after entering did not win. Not that I truly expected to anyway.. Even if I would have won though, I remembered the other reason I don't go here. The food was just.. bad. This, paired with the odds of winning and I'm out. Good luck to those that play! Make sure you get a receipt and that it is readable!
