I've forgotten to use them even in my hand, thankfully the lady at the tractor supply is used to my shenanigans and reruns my order when I come running back in with my coupon.I always forget the coupons, until I learned to keep them in your hand while you shop. Works for me every time. Because I have to put them down to get my wallet. And you're like, "Oh, yeah. Here I have a coupon for that."
