Mom saved S&H Green Stamps, and so did I. I remember sessions as a kid of her pulling out her stash and making us sit around the kitchen table, licking them and pasting them into the books.

I got my first sleeping bag and my first Coleman Stove with Green Stamps.

My local Grocery chain had a "Green Stamp" rewards program for several years in the early 90's, only instead of stamps you earned S&H points. Could use them the same as the old stamps or redeem them for the occasional $5.00 bucks off your grocery order.

I can't remember the name of the other similar "Stamps." They were yellow.
