Merchants are NPCs that can be found in almost any town or city. A player can buy various items from them; most notable among these are the Expert Salvage Kits and the Identification Kit. Even more important, a player can sell any of his items here and turn them into Gold. This is a major source of income for every player. Players should be careful when selling items, however, because once sold, an item can not be bought back from the trader. Also, other traders might offer a lot higher prices for certain items, for example Vials of Dye or Runes.
