Get ready to be sad panda's.  Thanks to this: https://money.cnn.com/2018/06/14/news/economy/trump-china-tariffs/index.html
you can expect to pay 25-30% duty on all cryptocurrency miners and a ton of other stuff coming from China.  I ordered 3 z9 mini's at an end price with shipping of @ $2500.  I had to fork over a COD check to UPS for $744 to cover the duties they paid before they would release the 3 miners to me.
