S7 @ 3.1BTC shipping 5 days after payment recieved is fool's gold!
Shipping from stock at what was at the time a price cut smacks of a clearance sale. The significance of that clearance by bitmain may simply be undermining a competitor or clearing space for the next generation BM chip. Either way, with the network diff they have to recoup as much as possible from their stocks before they become worthless.
I think the price is more a reflection of how much BTC has risen in value, rather than any fire sale. S7 have some way to run yet. Even with the Difficulty rises we are seeing and the halving still the best value for money miner on the market at the moment.
