Trade system thingy for Commerci.

I did the intro for it through Maestra Fiametta but I have no idea how to get to the actual system.

Did you do the light bulb quest from Cassandra, I think its Get Rich Quick? Then after that just talk to the NPC and click start trade or something like that.

You can never mind this thread, I figured it out and I placed it horribly in the wrong forum, I don't even know how I did that.
