I was going on about not having Green Stamps anymore. No one knew what I was talking about. They were the original rewards program. Stores gave you stamps based on what you spent. When you had enough, you filled up a stamp book. And with a few books you went to a "store" and could redeem your stamps for merchandise. My grandmother loved them. I remember we went once and got a coffee pot. There were Green Stamps and a competitor, Plaid Stamps. Now, no one has any idea what I'm talking about.
