I agree with your thought, I have always ordered my miners UPS from Bitmain and never once had any issues with damage or delay coming to my commercial address. The FedEx option was slightly less expensive but my track record with UPS has been great and I have a daily account with them so I picked that option
UPS has been great for me as well, but I had to pay some high import fees when I received the unit ($10 CAD to have UPS broker the package into Canada, plus ~ $121 CAD for import fees).
Have any of you guys in the States had to pay import fees on BITMAIN miners? I've heard from some people that they haven't had to pay any additional fees, might be a Canada-only type thing.
Miners are not subject to any import fees coming to the US, however UPS will charge its brokerage fees to handle the import.. It's more about the number of boxes than shipment value..
