Clip this: September is National Coupon Month

Along with Labor Day (Sept. 7), Grandparents Day (Sept. 13), and Stepfamily Day (Sept. 16), add this to your calendar for September: National Coupon Month.

That's right, the habit of getting out the scissors on Sunday mornings to clip coupons from the newspaper, or going online to print them from home, is honored with a month of its own.

The mighty coupon is celebrating its 100th anniversary in September, marking the time since the first true coupon appeared in 1909, when grocer C.W. Post offered a penny off his new cereal, Grape-Nuts.
