Buy from where many of us do: B&H (free shipping for over $50), or Freestyle (charges for shipping based upon cost of order, not size or weight). Freestyle may have greater choices, but with shipping costs, may be a little more expensive. Some labs and rental houses may have a limited selection as a courtesy.
Retrospekt south of Estabrook Park sells a wide variety of film in 35mm and 120 if thats what you're after. I don't know if they sell cameras. If you make the trek out to Madison the Camera Company sells both film and cameras though their prices and attitude can sometimes leave something to be desired...
registered just to post in here. go to mike crivello's camera in waukesha, they often have the best selection i've seen anywhere, and they keep the better stuff cool in a refrigerator.
Only places I know in E. Wisconsin is Murray Photo in Appleton, and Badger Graphic Sales in Kaukauna. Will have to keep Retrospekt in mind, thanks Finn Lyle. Murray has many color/BW 35mm and typically 120, and sometimes 4x5. They also have, or use to have a vast used film camera/lens/equip for sale. Murray stocks film and chemicals as St. Lawrence College has film courses. Badger does mostly online selling but if you call in an order they will have it ready for you to pick up. Either way you should call first if driving up.
As already mentioned, The large online retailers like Freestyle B&H or Adorama are very efficient and easy to order from. Unfortunately, many of the options for color negative films are regularly on back order but you can set an alert and if you respond quickly you will be successful in finding what you need.
