i also think that it would be nice if you merchants could give us some info about how much custom items costs? maybe there is one buyer who is willing to pay $100 for a special item, but you 'know' that you wont be able to sell enough $5-items to make it worth the effort. there should be some kind of "rentacoder" system where buyers can post request and get bids from merchants. this would also make it possible for people to specialize in buying and selling other peoples stuff, taking all the risks and rewards.
