I'm hearing people are winning often on this -- it goes daily through March 15 -- I won once (5 free 2-liters) in two days of playing it. Good luck! And thanks to Susan C. for this tip!

Note: Someone on FW posted an email response they got from Coke saying it was okay for multiple household members (specifically spouses) to both play the game. :)
