1) There are 0 gold sellers in this game. Haven't seen one since day 2 or 3 after launch. It just isn't profitable in this game. Kudos to Bioware for setting it up this way.
I've seen a few since release... far less than any other MMO tho and mostly it's done by mail rather than spamming general chat... tho it is nice every time I get one they also mail me 1 credit with the letter for some reason.... only need to get like 999,990 more credit farmer mails and I could buy myself something nice off them
