My film buying is not really connected to my current need. I buy when I think I can afford it or when I have a little extra money. Some years ago my mothers passing left me with some little amount of money. I bought a lot of film. And a Freezer. Even with jnanian's obsession with telling people they don't need to refrigerate their film and paper I absolutely do believe in it and have a zub zero freezer with a life time supply of 8x10 and 120 film... arguably life time. Not to mention a very important direct duplicating film in rolls that was discontinued years ago and arguably more than I will ever use. Aside from that when I find I have a couple hundred dollars to spend that wouldn't threaten my survival, I buy a box of 8x10 film.
