MINEOLA, N.Y. (CBSNewYork) – If you don’t happen to hit the Powerball jackpot, you might need to hold on to your coupons.

One thrifty shopper on Long Island did just that – for nearly four decades.

The store had to honor the ancient discount because it didn’t have an expiration date on it.

It saved the shopper a whopping 20 cents on some Crisco cooking oil.

A valuable lesson for those smart shoppers out there: it’s better (to save) late than never.
