There’s a trick to getting the most for your money from this deal. In order for the coupon to take off the largest amount, make sure the items are scanned in a certain order. When Walgreens has a buy one get one 50% off sale, the first item will ring up full price and the second will ring up half off. The coupon will get you free body spray. To get the maximum amount written on the value of the coupon, the body spray needs to be scanned first, and then the deodorant and then a body spray and so on.
