Just heard on the Springfield NPR affiliate, WUIS, that a stand-alone camera store is coming to Springfield, Illinois. The camera store is a chain based in Creve Coeur, Missouri, called "Creve Coeur Camera."
It's been more than ten years since there's been a stand-alone camera store in Springfield. I realize that they sell mostly that other kind of camera, but they have a pretty good selection of used cameras, and they have a selection of film that's comparable if not a little better than the camera shops in Bloomington and Peoria. They even have Ilford! Sadly, they only have one kind of slide film, Velvia 100F, however the prices are only a couple dollars higher than from the big two in NYC.
