wolfen.  This is strange, we are both right!

When I go to http://bitmain.com and click on their link to buy a S7 batch 8, the price is 2.49 btc or $1,031.31

When I go to http://bitmaintech.com, as you said, the price there is $1.607 btc or $665 for a batch 12 to be shipped on March 19.

Is http://bitmain.com some type of scam site?  I wonder.  This is strange.  I'm not really in the market to buy a S7 right now.  I have
several and many are not running 100%.

Buyer beware.
