Unfortunately CVS does not have a corporate coupon policy.
CVS' rewards card is called the Extra Care card. It's free to sign up and you can get one at your local store. In order to earn Extra Care bucks and get sale prices you'll need this card. Extra Bucks (frequently abbreviated here as ECB) are CVS rewards that print on your receipt for buying specific items. These can be used on anything in the store except for prohibited items like alcohol and tobacco. Extra Bucks will 'roll' if a deal limit is more than 1.
Most Extra Buck deals are limited to 1 per card, but the ads and shelf tags are very good at listing these limits.
When you enter the store, I highly recommend scanning your Extra Care card at the coupon machine. It will print store coupons tailored to your past purchases and also frequently for that week's sales.
At CVS you may use a manufacturer coupon and a store coupon per item. Overage is typically not allowed per their register programming but every now and then it does happen. It is CVS' policy to allow coupons for more than the item's price if the coupon is adjusted down to the selling price of the item. They are NOT supposed to refuse these coupons outright. CVS store coupons are one per transaction. If you try to use more than one of the same CVS coupon per transaction the second one will beep. However, if you separate those coupons into two separate transactions you'll be just fine.
CVS has a magazine that is frequently available called Reinventing Beauty (abbreviated frequently here as RIB). It costs $.99 but it has a mix of store coupons and manufacturer coupons inside. Stores also receive sheets of just the Reinventing Beauty coupons that they are supposed to leave out for customers to take without purchase. Many stores do not put these out, so you may not be able to find the sheets in your store. If you do you won't have to buy the magazine.
