I just ordered and received 8 rolls of Kodak TMax 400 in 120 from Amazon for a future event. It arrived with Free Shipping (USPS with tracking), no State Sales Tax and fresh dates in the 2013 range, all the same batch. I was impressed.
Price: $ 3.99 a roll (Minimum order for free shipping it $ 25.00)
They have other films as well. I never considered them as a film source before, but I do look for zero tax and free shipping in whatever I acquire.
