Be careful when dealing with Seri,
Looking at his profile his original posts were around borrowing
BTC against 1 million $ property equity
https://bitcointalk.org/index.php?topic=607339.msg6822027#msg6822027Then nothing for 6 months. He now pops up again posting in all hardware for sale threads and his profile shows the password has been recently changed -
May possibly be a hacked old account.
No offense intended Seri but better safe than sorry so would recommend no shipping first and Escrow where appropriate.
