Shipping allows the player to put various goods into the shipping box located near their mailbox. Gold is received the following morning. Iridium star quality items have the highest value, followed by items with gold star quality, followed by items with silver star quality, followed by items with no stars. The amount of money received from shipping is the same as selling to a merchant. The only difference is that merchants make payment immediately.
With the exception of Artifacts, items can only be added to the Collections tab through the use of the shipping box.
In order to ship an item, either walk up to the box and drag the item from your inventory to the shipping box, click on the box and select what to ship from the menu, or select it from the inventory bar, and right click the box. If a mistake is made and the wrong item is put in, the player can right-click the box and the last item added will be displayed, which the player can then drag back to their inventory.
