I was in K&M yesterday [Broadway location, below Walker St.] and they have ALL sorts of expired film for sale. Hey, it's fun for experimentation if nothing else. There was tons of Ektachrome 64T film - 35mm and 120 - as well as some Gold, Ilford XP, and some other sorts. Some was pretty old, and some was expired within the past few months.
Just thought I would give you a bargain-bin heads-up!
