In my experience, if there's a K2 version available, that's usually the version they offer. But not always. You have to try to figure it out from the listing (e.g., if it's the K2 version, it will usually be labeled as "remastered"). Coincidentally, I just received two K2's from them today--"Mulligan Meets Monk" and "Soultrane". Can't beat the price for K2s!
And if I were you, I'd check my queue once a day, if possible. You never know when one of those soon-to-be-unavailable warnings will appear.
