The easiest way to trade with other players is to make an exchange with them. Click on a player and select ‘Offer a trade’. Drag the items you want to trade into the exchange window and wait until the other player has done the same thing. After confirming what you’ve placed in the window, you can accept the trade.
Your Haven Bag is more than a house, it also doubles up as a salesroom that you can use to show off your wares! It comes fitted with a little vitrine in which you can put items up for sale. When you log off, the Haven Bag remains active and other players can continue to buy your items. You see, you can even earn Kamas while you sleep!
