When you make a payment abroad, there usually both sender and receiver bank fees involved.
So your bank takes a fee for the payment and also Bitmain's bank takes a fee for that same payment.
Bitmain wants you to pay these both fees.
This has been the case for a long time.
I remember things been the same when I ordered Antminer S2 back in the old days.
Thanks again for the reply. I understand the fee part, may be I was not clear with my question as to how much the fee is.
Thanks and I truly appreciate your help!
