So with the release & beta of Mists of Pandaria, Blizzard is implementing "Gear Vendors" that will provide you with gear that you may have missed on your way questing through a zone in Pandaria. Now I know there are Gear Vendors in The Jade Forest and they just recently implemented one for level 89's in Townlong named "Supplier Xin."
Have they established any other gear vendors in Karasang, Valley, or Kun-Lai? I searched for a long time for them, and I couldn't locate any beside the one in Valley that just sells the same ilvl gear that the ones in The Jade Forest do.
