Thanks @tcsmate, @3DBrushes, @Solutionbenedicts

Finally I am getting a deal on an Antminer L3+ for 2.2 lakhs and the guy says I should give money after testing and running the equipment, BUT he is asking for the Fedex courier charges upfront which he states will be around 7000. Now what I am thinking is if he can trust me on 2+ lakh why he asking for delivery charges upfront.

Iam confused!!
