Gene's Camera in South Bend, IN carries Kodak Tmax film in 4x5 and sells it at a reasonable price. I buy from them when they have it in stock. They're also willing to order Ilford Hypam fix for me along with their regular darkroom order and I prefer to buy it from them as it's expensive to ship heavy liquids. But the don't carry papers I use (Ilford Warmtone in 11x14,) or 8x10 film or... lots of other stuff, actually. I spend a lot at Freestyle.
