Did anybody else have to pay import duties (I'm US based) for the shipment? I have received a postcard asking me to go dhlmypayment.us
I saw the website but did not enter my information. More scam concerned than anything; never received a tracking number and my store account still says "processed".
Who did you order from? If you ordered directly from China or from the UK, you have to expect to pay customs duties.
All the same, in your place, I would neither pay nor accept the shipment, because it's tacit acceptance of their delivery. Their miners are already obsolete before you even plug them in. No sense in throwing good money after bad.
