If you don't want people to steal it make them give you 50 dollars, or 100 dollars, and then when they send it to the next person, give them the money back. Like a safety net. And if the person doesn't have the money, than send it to the next person, and when they do, then send it to that person and then continue with the list. Either way. You sell a HHKB for 50-100 dollars and they get a really good deal or they are trustworthy and send it on
EDIT: Also, I saw that photo of your macbook... What the **** is wrong with you, why don't you have the dock auto hide like a normal person
