I just checked out the coke rewards catalog and you can get 500 Priority points (NOW OUT OF STOCK) for 160 coke rewards or $20 off Southwest Airline Wanna Get Away fare for 100 coke rewards.
For the $20 off SWA there are several restrictions. It is for one time use on a round trip Wanna Get Away Fare only. Travel must be purchased 7 days in advance and purchases must be made from 11/1/12-2/1/13 for travel 11/8/12-2/16/13. Blackout dates are 11/21-11/26/12, 12/21-12/24/12, 12/26/12-1/2/13, and 2/15/13.
Also don’t forget that from 11/7/12 – 11/24/12 you can get double rewards on Powerade, Powerade Zero and Coke Zero caps.
If you want to earn 20 free my coke rewards, Family Dollar has a game you can play. Follow these instructions below. HT to Tarheelblue on Milepoint. Got my points! (UPDATE: You can only earn 20 points once per email, they must have fixed the glitch)
