My grandpa was the most frugal person I ever knew. He reused everything, saved every spare coin, and believed nothing should be wasted if it still had value. So when he passed away and left me a sealed envelope labeled just for me, I assumed it would contain something small or symbolic. Inside was a single coupon offering one hundred dollars off an in-store purchase. It had no expiration date and listed a store I barely recognized. At first, I laughed, thinking it was his final practical joke.
For several days, I kept the coupon in my wallet. Throwing it away felt wrong, even if it seemed useless. Eventually, curiosity got the better of me. I found the store tucked into a quiet shopping strip and went inside. Everything looked ordinary—bright lights, stocked shelves, nothing unusual. I picked up a few basic items and handed the coupon to the cashier. The moment she saw it, she paused and called for the manager, who examined it carefully and asked where it came from.
