As you see, when we ship the item to you for the first time, we paid the postage.
And if you do not pick up the item from the post, the post office will return the item to us and charge the shipping fee again.
And if we ship the item to you again, we have to pay for the postage again. That's mean we have to pay for the postage for three times. We have already lost much money in this transation.
