It is somewhat YMMV. I performed a search (On Saturday, Feb 20th) at the POS at my store, and almost all stores within 50 miles of me had at least 1 in stock. (I'm in Zanesville, Ohio). Our location had 2 copies left. My guess is that the other stores may not have performed the markdown yet (I'm pretty up to date at my store, whereas some of the others take quite a while to actually reticket their markdowns).
I'm pretty sure that this is nationwide, since the PLC came from corporate. Usually corporate won't issue a PLC unless there is enough locations with stock left to get rid of. (If there is too little to bother with, they'll usually just issue a penny PLC, and have the locations with remaining stock send their items back in for credit).
As for there being a K-Mart clearance thread, the ones that came up in my search were all closed. If there is still an open K-Mart clearance thread somewhere, I apologize for not posting there. Believe me, I made the best effort to locate it.
