A money-back guarantee, also known as a satisfaction guarantee, is essentially a simple guarantee that, if a buyer is not satisfied with a product or service, a refund will be made. The 18th century entrepreneur Josiah Wedgwood pioneered many of the marketing strategies used today, including the satisfaction-or-money-back guarantee on the entire range of his pottery products.[1] He took advantage of his guarantee offer to send his products to rich clientele across Europe unsolicited. The money-back guarantee was also a major tool of early U.S. mail order sales pioneers in the United States such as Richard Sears and Powel Crosley Jr. to win the confidence of consumers.
