I just got this email from My Coke Rewards. Enter enough codes to earn at least 10 points in your My Coke Rewards account this week and next week you can get 10 bonus points. You must sign into your account next week to receive the 10 Bonus Points.
A coupon valid for a Free Coca-Cola 20 oz is only 30 points. Most 12 pack and bottle caps are worth 10. I need to enter some points to get a few coupons!
