I do get some film from cheap shots AU and for most films he is a bit cheaper than Vanbar but unfortunately not for Tmax , Vanbar is around the $85 for a 50 sheet box and cheap shots is over $140 for the same box.
Most other films are maybe a bit cheaper buy around 1 % but I find 35mm to be rather cheap from cheap shots AU.
I have always liked FP4 with medium format but have never tried it with 4x5
