Apparently I've been collecting these for a lot longer than I thought. We unpacked a box that we packed when we left Utah--in 2004. In it, I found a couple of clippings from an old Macey's ad, with a couple of these circled:
"Clean and Smooth 64 oz Anti-Bacterial Soup $2.99"
There was another one. When I find it, I'll post it, too.
