If you’re new to CVS, one thing you have to know is that they have a unique policy on how coupons can be used on BOGO free sales. Unlike many other stores, you can actually use a coupon on the free item in a BOGO sale! This week, we have a perfect example of how that can help you save big. Pick up two Right Guard Deodorants for the price of one. Then, use two $1.00 coupons to pay just $3.00 out of pocket for both.
