CatFish; I totally forgot the S & H Green stamps !!! Killer memory Brother. My mom God Bless her still had the S & H paper "books" you placed them in to redeem.
I also loved the Orange 76 antenna balls they gave out ( I still have a "bag" packed away somewhere; God knows where ??? ) ; the Exxon Tiger stickers you could get and Standard had some type of Hawaiian Flower Stamps you could get; fill a card out and win prizes !
I worked for Lowes Foods for 12.5 years. During that time they reintroduced the S&H green stamps program. Books, stamps, and all. It was only meant to be used to redeem for specially stocked giveaway items (plates, silverware, cookware, etc). That was in the early 2000's. This program gave way to the S&H card, a card with those same benefits. That was then transitioned to a purchase-tracking/reward card just like all other stores have. This card not only is required to receive sale prices, but it accrues points which are redeemed for discounts on fuel at local gas stations.
