There is a great camera store in Savannah, GA called Bay Camera Company. I went there last winter and it seemed like it was primarily a spot for developing film and buying film and paper; i.e, there were very few digital cameras lying around and camera sales seemed like a small part of their business. I bought some fresh Portra 400 in 120 for not too much more than I would have paid at B&H. I don't know that they handle sheet film but I spoke with the owner, who still shoots film, and he would know where you could go.
