I have some expired 120 xp2 as well; the local "pro" lab here in Ottawa does develop it, and will return it uncut, but last time I did some, they charged $7.00 per roll. For me it is cheaper and much easier to purchase new 120 film and develop it at home in D76. The stuff is in the freezer at home; undecided what to do with it. Agree with other posters; the stuff I have expired 1986, was stored well, and still works just fine.
(much easier?? most of the time I use my bicycle to get to work; if I go during a work day, it is about a 4hour round trip cycle - that's a long lunch break!)
