I use to work at Amazon and they didn't sell used shyt as new. It was either product sold by a 3rd party on Amazon, or some employee opened the box to check out the system.amazon has pulled that kinda shyt before. My brother in law bought something new from Amazon proper but it was some shyt someone returned.
I was there around the time the ps4 launched and people would open the box to see how the controller felt before packing it.
