I crossed paths with a friend at the first camera club meeting I have been at for a while. He has transitioned away from film for IR work now. Pete has 42 roll of 120 format film, Ilford SFX, expired 2008. It has been in the deep freezer from the day he bought it a few years before it expired. He paid $10 a roll when it was new. www.gulliverphotography.ca is his site. Get in touch to see what sort of a deal you can strike for the quantity you want.
