Oh... Film!
Other than the stuff I've recently bought - which undoubtedly cost more here than in the US, I have:
120 - 5 rolls of Kodak Portra 400 NC dated 2001
4x5 - Fujichrome 64 RTP, 10 sheets, never opened, dated '85
Fujichrome 50 D, 10 shhet box, opened, number unknown, dated '85
Kodak Vericolour III 6 sheets, dated '86
Kodak Proffessional copy film, 100 sheet box, opened, feels heavy, number unknown, dated 82
I got all this from the last proffessional lab in town when they were closing down. It has all been in the freezer since I got it, and he got it out of his. There were other open, outdated boxes which I have used which were all fine, so I assume these are too.
