No, I've got a new invoice. I ordered 200 GH/s for ca. $1,200 and I got an invoice for $3,499 for 600GH/s.
I think the customs declared value should be what we paid for them, at most. Even better, would be their market resale value now. No-one would spend $3,499 for 600 GH/s today, you can get over 1 TH/s for that.
