I like the way they are doing the drawings. If you piled up a ton of these things, you could give yourself a pretty decent chance at winning one. I suspect though, as the contest draws out the entries will start to get higher and higher as people are doing exactly that - putting their stockpiles into one single drawing to increase their odds.
Congrats on the win! That's awesome. I don't drink soft drinks anymore and my wife rarely does either so I've only had 2 entries to use
