Just to warn everyone on Harbinger, there's at least one player (The name was Kamille with an accent on the a, I believe) who will offer to trade a Dathomir Rancor or a Walker mount for a pet that is worth far less, like 2-4 million credits. That's because the player is buying up all of that particular pet (Which is maybe worth 100k) and then listing them at the higher prices, and when you buy one of the overpriced pets, Kamille (Or whoever) will say that it was too late and they already made a trade with someone else.
I've heard it happening to other people as well on Harbinger.
Essentially, if a deal is too good to be true, at least on our server, it is.
