Fenced items, just because the thieves guild members in Oblivion were the nicest people in the game. I'd help the poor smucks by buying expensive clutter they took of some posh bosmer. So yeah, I buy stolen goods, use a middle corperation, aka the Cyrodil merchants guild to send the stuff to Morrowind where it's sold for high profit!
Either that or I sell pies in the streets of bowerstone. yeah, sounds more like me.
Edit: wait, WoW as well? then things change a little.
Potions and Alchemical supplies, I would have my own little shop in Bilgdewaterport.'
And I've got the best deals anywhere. I was planning to call shorten the word potion for the name of the shop but then it would be potshop, and somehow I don't think the bruisers would fancy that... unless goblins are liberals... wich they are... oh well let's just increase the amount of wares I got in my herb selection then. hehe
