Add what you want to buy (price, store) and the deals you have: “spend X, get Y off” at a store or across the whole site, “every X spent, Y off”, coupons, % off. It tries every way of grouping items into orders and every way of using your coupons, and prints the cheapest plan as a receipt. Mark items as “Maybe” and it tells you which add-ons make the total cheaper, and by how much. The sample items, prices and deals are made up for the demo. The cover picture is AI-generated.
