Thanks for your interest!
There is only one way, in case the miners needs to be shipped outside from china. (Sea freight)
I will need to check the rates but the sea freight will be around 500USD-1000USD for the full lot and needs around 3 weeks, depending on the location.
Shipping overseas for 39 units is already around 4000USD. I have confirmed that with a representative. So I'm not sure how more it's going to cost for 11 more units.
