Well, my DVDStars order of volume ten is still pending after 6 days. It has a shipping estimate for the 18th. I really doubt I stumbled across a site with it still in stock for close to list price though. I'll report back here if I actually get it.
And for those collecting:
MST3K The Movie is out of print, but a German Region 2 is currently available apparently and it has the english version on it so if you've never seen it and always wanted to importing this might be worth it. I thankfully picked up the bare bones dvd back when it came out for ten dollars, but I'm still hoping for a re-release simply to get my hands on some extras.
Beginning of the End went out of print a while ago.
Volume 1 went out of print but is now back in print.
Volume 3 is apparently going out of print due to Sidehackers. Despite that is still seems easy to find new since I got one last week for about $33.
Volumes 5, 7, and 8 are not out of print but they apparently have problems.
Volume 9 has all of the signs of being out of print, but I haven't seen any explanation as to why.
And Volume 10... I'm hoping Canada forgot to ship theirs back to Rhino.
