Didn't find this posted anywhere. Coke has a contest connected with the Olympics. Enter codes and you will be given an Olympic event. If the US wins any medal in that event you will be sent a coupon for 5 2-liter bottles of Coke (maybe 5 coupons for 1 2-liter, not sure). Codes can be found on marked packages of Coke products, but you can get 3 codes per day via email on the site. Codes will be emailed to you then you go back and enter them. Do not copy and paste the codes as they will not work, codes must be entered without the spaces. I just found out about this yesterday, six free codes, 3 wins (15 2-liters), 2 losses, 1 pending. My wife has 1 win, 3 losses, and 2 pending. Good luck!
