Remember S&H Green Stamps? Remember getting them after certain purchases depending on if the business participated in giving them out with those purchases? Remember the box or drawer they were stored in until it was time to glue them in the books before redemption? Remember having to lick the backs of the stamps to put them in those books? Remember the taste in your mouth after licking so many stamps because your parents waited until the box or drawer filled up before putting them in the books? Remember looking through the catalog or going right down to the redemption store to shop for something for the family for which to trade the stamps? Remember, after you thought they weren't redeemable anymore, wondering what to do with the stamps you found in your parents' attic, or basement, when helping them clean out when they were downsizing, and then tossing them because you didn't think they were valuable anymore?
