The word old navy canada promo code has been adapted from the French couper which means to cut. It appeared in the English dictionary for the first time in 1822. Discount coupons became known in 1887, when Asa Candler, as a marketing strategy for the launch of Coca-Cola, used the distribution of printed vouchers in magazines that could be exchanged for free soft drinks in stands. This strategy, considered aggressive at the time, was one of the factors that resulted in the success of the brand. This was the first time in history that coupons have been used effectively to attract customers and expand sales of a product.

In the 1930s, the use of coupons spread throughout the Great Depression, by people seeking to find grain and other products that were missing from the market. From the 40s and 50s large supermarket chains and home appliance stores began to use coupons systematically reaching more than half of American households in the 1960s.
