Head to your nearest CVS Store and score one FREE Green Bag Tag after ExtraCareBucks (tag costs 99 cents and you get 99 cents ExtraCareBucks when you purchase 1). Simply, put the Bag Tag on your reusable and they will scan it each time you make a purchase. Every 4th visit you will get $1 Extra Care Buck (ECB) to use on your next purchase. An ECB is basically FREE CVS money. Thanks 4Our2Cents for sharing.
