Did you know that CVS is one of the few stores that will allow you to use a coupon on the free item in a BOGO sale? It's one of the many things that I love about shopping there. And this week, Sundown Naturals Gummies vitamins are on sale, buy one get one free. Pick up your choice of vitamins for as little as $9.29 for two bottles. Then use a $3.00/2 coupon and pay just $3.15 each. That's a 66% savings!
