I'm very familiar with SupeRx, it being the local drugstore of my youth; but what about the others? I've heard of combined food-drug stores from the early 1980s carrying "Kroger Sav-On" branding, and I've heard that Kroger purchased a New Jersey Sav-On chain around the time it was first setting up SupeRx Drugs in the early 1960s, but I don't know much beyond that.
Just what and where were these SupeRx-affiliated Sav-On and Thrifty stores? I'll take it these had nothing to do with the western drug chains of those names...
