The companion https://wotlk.cavernoftime.com/item=38050 is missing in the coin store.
I suggest to add it for 15 coins to all Wotlk realms (including Blackrock).
It's a unique companion because it sells you cosmetic items in exchange for Ethereal Credits, which you receive for every honor/experience granting mob you kill while this guy is at your side.
The Soul-Trader was on retail only purchasable through loot cards and can't be acquired ingame.
