A local shop has 100' of expired (2008) tri-x for $25.00. It's been sitting on the store display shelf in relatively constant 70-75 fahrenheit all that time. If I were to purchase it, about what kind of weirdness should I expect of it? I would shoot a couple short rolls at different ratings, but any testing ideas would also be appreciated. Sitting right next to it, they also have a reel of Tmax 100 expired around 2006 for $40. I don't know if I want to go that far back, though. Any suggestions?
