Double MyCokeRewards points on 12-packs for a limited time

Remember all those free 12-pack coupons you won from MyCokeRewards back here?

Redeem them for diet 12-packs.  Get the codes (you can put a piece of tape over the opening to keep the cans in the box) and enter them from today to 1/19/13, when you can get double points (20) for the code.  40 points gets you a free 20 oz. bottle of a Coke product, so redeem just two codes for a free bottle.
