shipping (<$100)
Probably wrong. I just did a quick search on UPS.com (guessing at the exact size and weight, but I was probably close) and it came up at around $300
I also suspect that Bitmain is paying more than $100 to ship each Ant across the world in two days. When my last batch of Ants came, the UPS guy even said that someone paid big bucks to ship the Ants.
Considering each Ant is making less than $20/day now, perhaps Bitmain can reduce the price of each Ant by offering slower shipping.
