I had occasion to be in our local "UPS Store" to send our faulty Furion back. I noticed a sign advertising postal boxes with "a physical address". It would seem to me that you could receive items that can normally only be sent to physical addresses there. I have no idea as to how you would arrange that. I would imagine you could stop in at a UPS Store wherever you are and make arrangements to have something delivered to wherever you are going to be?
Just thinking out loud
