Thanks a lot for your reply, Turtle420.

Im actually aware of this kind of suppliers. Im trying to comfirm its experience and reputation before any advanced payment.

I asked for samples before, and they agree. And a initial order of some hundreds, and they agree too.

They ask 30% in advance T/T, and rest before shipping. I agree with 30% in advance, but demand and escrow service for the 70% left. They agree. Im seeking for a preship inspection, too.

But im very concerned about a fraud. So any advise are welcome. What else can i do? (you can answer by PM, to keep clear the thread)

Thank you very much, Turtle
