As it happens I was in a convenience store earlier today, and they still have a small rack with some film - a bunch of disposable cameras, and some individual rolls of Kodak Gold 100 and Konica Centuria 200 and 400.
I guess the Konica was from the later production runs, as a random sampling of film boxes shows expiry dates of 08/2008 and 09/2008.
I don't see this film around much - is the 200 or 400 anything special (vs. Kodak or Fuji consumer films)? A brief Flickr search showed some pretty average stuff - not bad, but nothing that immediately jumps out at me as being exceptional (colours, contrast, etc), but it's difficult to tell from low-res web scans.
They were all individually boxed, and weren't cheap - ~$6 each - but I can't imagine they go through a lot of it, so if it's worth the trouble I might talk to the manager about taking some of it off their hands for a reasonable price.
