Traders buy and sell items

Traders buy and sell items that you can use to alter existing ones or to create new items. Traders base their prices on what the market is currently offering, so you must get a price quote when you want to sell or buy an item in a Trader transaction. Traders deal in dyes that you can use to customize your character's armor, runes that add powerful bonuses to weapons and armor, and scrolls that improve Experience gain. There are also Traders who deal exclusively in materials (either rare or common) that Weaponsmiths or Armorers can use to create new items. If you're simply out for gold, you can usually get a better price for your materials from Traders than with a Merchant. The Trader's specialty is indicated after the NPC's name ([Dye Trader] for example). http://www.guildwars.com/gameplay/exploring/townlandscape/
