While on a shopping trip, Caroline is aghast to find out that Max uses coupons to help reduce the cost of food. Her outrage is short lived, however, when she realizes just how much money can be saved by clipping coupons. Over the next few days, Caroline becomes a coupon diva, buying up anything she can as long as the price is right. Max’s patience is tested when Caroline, instead of taking a trip to visit Chestnut like she promised, goes head to head with the self-proclaimed "Coupon Queen" of Brooklyn. In the diner, Max fights what she perceives as injustice when Han raises the price of tampons in the bathroom from a quarter to seventy-five cents.
