Well I paid £90 with UPS per miner and I am paying £65 with DHL however DHL is sllloooooow.
Also I was bit disappointed that the Bitmain is shipping us used miners but considering it is cheap and I can receive it within days and they do have an OK customer service that actually reply back to you it makes it OK. I really hope they will ship brand new Antminer S2 rather mine with it for weeks (or even mining now considering they are selling the old machines) and ship us the used miners.
It seems to be a industry wide problem that manufacturers mine with the machines for weeks and then ship the miners. This is far worse with pre-orders.
It's not a problem if they deliver on time. The only reason so called "pre-mining" is a problem is when manufactures fraudulently advertise and early delivery date and then delay the delivery date in order to charge a higher price and still use the equipment to mine for their own account.
