I do remember them. In fact, every time I sit down in the master bathroom, I look right at a two level cart that I got with Green Stamps more years ago than I usually admit to. It is a sturdy metal, and some years ago I cut out new 1/4 inch plywood boards for new shelves, but otherwise, except for spraying it black, it's the same as the day we brought it home.
Every now and then while decluttering I run into a couple of the S&W Green Stamps and they sure do bring back the memories. If we ordered anything from the catalog that they didn't have in the small store, we'd have to wait till it was shipped and then pick it up. I was always happy to get that telephone call from them.
