If you collect My Coke Rewards points, you might want to be aware of a limited-time promotion for college football season.
Now through Oct. 15, enter four codes from specially marked 12-packs of Coke products, OR two codes from specially marked 20- or 24-packs of Coke products, and get a free college team T-shirt.
There are 33 different team shirts available, but it's while supplies last. It does appear you have to have codes from the special college football packages of Coke, so you can't redeem points you already have in your account for this prize. Here's the link to the promotion.
(And if you drink a lot of Coke, you should really do the My Coke Rewards program. At the very least you can redeem your points for free Coke.)
