When you visit the CVS Coupon Center (AKA Magic Coupon Machine) make sure you register for the Double Quarterly ExtraBucks Rewards, which will now give you 4% back on everyday purchases.
One BIG thing to note is that if you do not spend $12.50 in qualifying purchases or do not otherwise reach a minimum in ExtraBucks Rewards by 12/15, will not receive rewards and will not have their earning carried over.
Note: This promotion does not apply to circular ExtraBucks Rewards. Your quarterly ExtraBucks Rewards will double to 4% on all eligible front-store purchases fro 9/16 to 12/15. Quarterly ExtraBucks Rewards will print on your receipt 1/1/13 to 2/14/13.
