Antiquity During the great famine of 18
AH (638 CE),
Umar, the second ruler of the Islamic Caliphate, introduced several reforms such as the introduction of
food rationing using coupons, which were given to those in need and could be exchanged for wheat and flour.
1900s Coca-Cola's 1888-issued "free glass of" is the earliest documented coupon. Coupons were mailed to potential customers and placed in magazines. It is estimated that between 1894 and 1913 one in nine Americans had received a free Coca-Cola, for a total of 8,500,000 free drinks. By 1895, Coke was served in every state in the United States. In 1929,
Betty Crocker began a
loyalty points program and began issuing coupons that could be used to redeem for
premiums like free flatware. In 1937, the coupons were printed on the outside of packages. The loyalty program ended in 2006, one of the longest loyalty programs. In Australia consumers first came in contact with couponing when a company called
Shopa Docket promoted offers and discounts on the back of shopping receipts in 1986. ==Types and uses==
