Always wonder how coupons got started? Here's a coupon fun fact.

Since C.W. Post distributed the first grocery coupon for a penny off his new
Grape Nuts cereal in 1895, coupons have grown into a staple in U.S. households.
Since the Depression, shoppers have looked to coupons to boost their grocery
budgets, most of them saving 10 percent to 20 percent on their grocery bills. For
many people, that adds up to between $800 and $1,000 a year.
