Quad - $640 = Temporary pricing. Ends May.
Double - $480 = Standard price
Single - $400 = Standard price
You sure about that?
Dual version US $640 (discounted US $480)
Single version US $480 (discounted US $400)
I look the discounted to be pre-order special pricing so $640, $480, $400 is apples to apples right?
Based on their quad thread.https://bitcointalk.org/index.php?topic=78239.msg870881#msg870881
At 640 USD through end of June (not May). Price to go up 50%. Some confusion on this thread. Not sure what's up.
