Term loss leader Definition: Products sold below cost by a retail store in an attempt to attract buyers who are likely to buy other, more expensive, stuff. Stores are very fond of advertising and even selling popular products at very low prices. However, they hope that once customers have seen fit to enter their stores, then the suckers, er, customers will decide to buy other products that aren't so popular or so low priced. These popular, low-priced products are loss leaders. Sure the store loses profit on the products, but they make up these loses on other stuff.
