Be very careful when you check out. Make sure all your coupons, rewards dollars, and discounts went through. I made the mistake for not checking while I was still at the store, even though I was surprised by the high amount. This was my first time using the CVS app on my smartphone and the less than enthusiastic cashier just wanted to get rid of me so I wasn't paying attention. Going back to the store today - I missed out on $11 dollars worth of savings. :/
