Enter the Mars candy company’s Be on the Field game to win various Superbowl-related prizes, including tickets to the game and celebration afterward.  You need to enter the UPC code from most of the candy line – and since I always have a few Snickers laying around…

Says you can enter up to five times per day, but I just tried using the same UPC and it said it was already used, so my guess is you’d need a bunch of different UPCs per day.
