Do you remember S&H Green Stamps?
You would receive them at grocery stores, department stores, gas stations, etc. You would receive so many according to how much money you spent. You would lick them and stick them in little books and then redeem them for merchandise.
You would get the S&H Green Stamps "IdeaBook" catalog filled with all kinds of things. Dishes, lamps, sheets, towels, and many, many other things.
I remember my mom would get all kinds of neat "stuff" with the stamps we collected. She got pots and pans, wall hangings, flatware and so many other useful items.
