A good which is priced low, possibly even below cost, to attract customers who are expected to buy other goods which yield a profit. The use of loss leaders can be profitable only if consumers are more conscious of the relative prices of some goods than of others.

Selling cheap goods about which customers are well informed may be used to attract custom for other goods on which they are less well informed, and can therefore be exploited.
