I'll answer my own question should anyone else want to find French RCIR's. There is a flea market in North Paris called Les Puces de Saint-Ouen. (The Fleas of Saint Ouen). This is much like a US flea market, except the most of the stalls are the storefronts on the streets of the Saint Ouen neighborh...

I'll have a week in both cities, so does anyone know any stores/flea markets to visit for CH and FR MRE's? Any help is greatly appreciated.
