There actually is a market for old, expired pack film for these cameras. I had a stash of 665 in my basement I decided a few months ago I was never going to actually use. Most of if nearly two decades out of date. Put a couple up on eBay for what seemed like crazy money (based on recent auctions) with the usual disclaimer that it was expired and not guaranteed, and it got snapped up immediately, and the buyer contacted me directly to buy any more that I had. Expired film obviously carries a risk, but I always found it was extremely rare to get nothingwhen I used to use it, and often got something pretty cool.
