I still remember the livingroom table lamps my mom got with S&H green stamps. They are in a picture I have from when I was about 5.
Another grocery store gave Gold Bond stamps. I think I got a playpen that I never used, except for a puppy, for my first son in 1977.
Plaid Stamps were from another grocery store yet, maybe A&P. I know I got a Bonnie The Plaid Lassie doll in a Christmas exchange from my uncle who managed an A&P. Wish I still had her. She was a nice doll.
