Item Requested: Whatever item from the list your character is interested in!
Trade Offered: The even trade your character has to offer. Remember, while physical goods are lovely (and will often be added straight back into the trade stock), skills and services are equally prized! Don't be afraid to offer up your master electrician or amazing chef for favors.
Dealer: Would you like to trade with someone specific? If you don't care or would like to roll the dice, just state no preference!
Other Questions/Comments: Anything else you want to specify/ask!
