Has anyone in the U.S. had problems with customs? My packages got held up and had a status of "A valid tax ID or deferment number is missing and is required for clearance." They were in Anchorage, Alaska when I got that status update. Customs and/or UPS is telling me Bitmain didn't put a tax ID on the boxes and they had to have my SSN and I'm going to be required to pay a tax on them now. What the hell...
