If a person gets Bus3, which has vendor +1, can they only place one vendor, or one vendor per house? If I "purchase" a vendor from someone else and place it in my house, what happens if they quit playing the game, or change their skills to something else? Could a vendor I buy from someone just disappear one day with all items on it because of this? Finally, I am looking for someone to supply a vendor on the Naritus server. Email Boozer if your interested.

Thanks!
