satisfaction began to spread. Many firms today offer money-back-guarantees for a few weeks or months, but

L.L. Bean offers a complete money-back guarantee. Customers can always return anything they have bought

from L.L. Bean, no matter how many years later or what condition the product is in, for a full money-back

guarantee.

L.L. Bean has very few stores. Instead, most of its sales are made by mail, telephone, or, now, through their

website. For this kind of firm, imperfect information may be an especially difficult problem, because

customers cannot see and touch what they are buying. A combination of a money-back guarantee and a

reputation for quality can help for a mail-order firm to flourish.

Sellers may offer a warranty, which is a promise to fix or replace the good, at least for a certain time period.

The seller may also offer a buyer a chance to buy a service contract, where the buyer pays an extra amount
