I have two rolls of Kodak Advantix 400. It has an expiration date of 06/2004. I got it a year or so ago from a thrift store (I don't know why) and it's been in my fridge since. I have no idea how it was stored before that.
If you're interested, send me a PM. I also have a couple APS cameras.
I have some in the box:
2 each 100 speed 25-exp date 1/1998
1 each 400 speed 25-exp date 9/1997
2 each 200 speed 25 exposures date 10/2003
2 each 200 speed 15 exp date 11/2003
