Win a coupon in the Cargill Dinner in 20 Sweepstakes or this fun Hamburger Timer. There are 400,000 coupon winners and 1,970 Hamburger Timer winners (ARV $5.70) in this sweepstakes that ends November 20. Unfortunately, you do need a game code to play this game. You can only get a game code without purchase if you mail-in your request (not worth it in my opinion). So keep your eyes peeled at the store for stickers on ground beef with this hamburger timer and a game code on them! If you find these game stickers, let us know what store you shop at.
