The Trade feature allows all players to sell items in their shop. There are several types of shops available: Regular, Premium, Legendary and so on. The higher the tier, the more items you may place in the shop. Shops remain open as long as you're online (unless you've got a Premium shop with 'offline' duration). Shops will close when you log off or change to a different channel.
