Starting 02/09 you can get a free Rockstar or two!! Yay!
How the deal works:
Buy (1) Rockstar @ 1.00
Get back: 1.00 RR
Remember with Register Reward you can't use one to pay for the same product, so if you want more than 1 you will need to either pay out of pocket for each or use a RR or Balance Reward points.
