January 17, 2021

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.
