"Coupons put in their place!" from Blue Cricket Design.
I am sooo bad about taking coupons and forgetting to use them. I'm not sure that coupons save you a whole lot of money, but there definitely won't save you anything if you don't remember to give them to the cashier.
This handy shopping organizer is super cute. And, just removing it from the cart would remind you to hand your coupons over.
