"PandaWoW Administration does not sell any characters and only provides a platform for trade. Thus PandaWoW is not responsible for characters in control panel sold by players and not responsible for appearances, races, factions, presence or absence of equipment, inventory, mounts or ingame mails (even if it has been declared to the buyer), PandaWoW does not give coins back, exchange characters or items and does not give items if the buyer declares that any items are missing. Transaction cannot be canceled for any of the above reasons."
