Method

1) Find yourself a Serial number, for the Playstation 4! You could do this by going on to eBay, Craiglist etc.
The reason being is because most sellers are most likely to upload pictures of their serial number which makes it easiers for people like us to Social engineer the product!

2) You want to have balls for this, so you want to call up Sony and tell them that the Playstation 4 does not turn on. They will go through their TS who will setup a repair. (It's best if you don't have a PlayStation account as it will make it seem less suspicious)

3) Now you want to wait for your box and you box them with anything as they do not check the weight so it does not matter what you box them.
(IMPORTANT NOTICE: THEY REQUIRE A RECEIPT COPY WHICH THEY DON'T VERIFY. HOWEVER, YOU WILL ALSO RECEIVE A PINK PIECE OF PAPER THAT CAN BE RIPPED OFF. YOU WANT TO FILL THAT OUT WITH YOUR SR# AND YOUR DETAILS. YOU THEN WANT TO PUT THE PAPER AND THE RECEIPT COPY IN THE BOX.)

4) Now you want FedEx to pick it up or drop it off somewhere.

5) You then want to call them up every now and then check in on the status

6) Within 1-2 weeks, you will have your Playstation 4 in your house! Good luck!
