Send a friend a FREE Coca-Cola on facebook

Once you have installed the app Coca Cola Ahh Giver on facebook, you can post a message to your friend's facebook page featuring Coca Cola's cute Polar Bear.  Once your friend clicks on the message, they can print off two coupons for 99 cents off a 14,16, or 20 oz bottle of Coca Cola.

ETA: There is a limited number of these coupons, but a fresh supply is added every Monday.  I tried it today, and I was able to print two.
