Gemco? The Gem Department Store chain. My parents shopped at the Gemco on the Berlin Turnpike. Now it is a Price Chopper Supermarket.
I feel like I'm in the Amesfanclub.com forum. Great site about old store chains.
Gemco was a division of the Lucky Stores, which was one of the largest supermarket chains in the west until being acquired by Albertson’s in the 1990s.
Gemco was similar to Target and Walmart except you purchased groceries in a separate part of the store. That was done because the grocery workers were union and the rest of the store workers were not.
