Shipping
Shipping allows the player to sell items by placing them into the shipping box located near the mailbox on The Farm. Gold is received the following morning.
Iridium quality items have the highest value, followed by 
gold, 
silver, and regular quality items, in that order. The amount of gold received from shipping is the same as when selling to a merchant. The only difference is that merchants make payment immediately.
The shipping box opens its lid when the player approaches it. To ship an item (or stack of items), approach the shipping box and "use" it (right-click on it), then left-click on the item in inventory. Alternatively, you can select an item in inventory, approach the shipping box, and left-click on the box.
If a mistake is made and the wrong item is put in the shipping box, you can "use" the box at any time during the same day, and the last item shipped will be displayed. You can then click on that item to add it back into inventory. Only the last item shipped can be retrieved.
