Anyone here bought from grey market internet seller?

[dingding777]

I asked yesterday about buying from gemnation.com, but no one answered, so I guess no one here bought from them before. So I want to ask for generic quesions on what should I pay close attention to when I buy from internet grey market seller. Can someone recommend some grey market sellers that are trustworth? I have read a lot storied on sending out money but received nothing or received something fake. As a first time Rolex buyer, I want to be very careful.
