I’ve got about 80 of these and would like to sell them in bulk. (Horde - Hyjal… I posted on a different character accidentally)
They tend to sit around 75k and are no longer attainable in game. People mostly use them to skip WoD content while leveling using the bonus objectives. They go up in price near the end of expansions when people level their alts.
If interested, make me an offer and how many you want to buy.
