Extra Care Bucks (ECB):
ECBs are coupons which print on the bottom of your receipt after buying the specified item, or dollar amount of product. These coupons, can in turn be used to buy other items in the store. In order to receive these coupons, you have to sign up for a CVS card and scan it every time you shop at CVS. You can combine coupons with the ECB items and still receive the ECBs. In this way, you can make money on items. There is usually a limit of how many times you can get the ECBs. The ad will list the limit.
