I had the same problem with the Dexter Gordon set recently. I get the feeling they aren't too concerned about the website being accurate. They did refund me right away when I asked, though.
The Rollins Village Gate box, the Earl Hines Mosaic set, and just last week the Sidney Bechet Bluebird Sessions box, which I've been looking forward to getting for a long time.
I forgot about the Jazz Tribune/Indispensable series. I'll have to look and see how complete that is, although those are kind of hard to track down these days, I think.
