I know this would kind of beat the purpose of the traditional vendors, advertising on forum etc but I really think having an actual market within client to auction/sell things as a starting bid or buy out would be beneficial. Have the items up and running for 48 hours then place them back in the owners bank if it hasn't been sold. It would make things easier to sell and if people are specifically looking for items they could simply type it in the search and it'll show the item with different prices determined by the sellers.
