Okay so armed with 9 ecbs and some coupons, I went to CVS. I got the 2 things of toothpaste, which was suppose to get the wisps for free, but they ended up on my reciept and I spent 3ish oop. I got back 5 ecbs. I then went back and they looked at the flyer and there was a 2 pack for free, but I had a 4 pack, but there was NO 4 packs in the store. So they refuneded me the 1.35 the 2pack would have been worth, so yay for that!!
