Amazon has Windows 8 Pro + $30 credit for $69.99

As if Amazon wasn't doing well enough with Windows 8 sales, seeing pre-orders dominate it's Best Sellers list, they have decided to sweeten the deal. Now you can pre-order Windows 8 Pro for $69.99 and get a $30 Amazon credit to boot. For those of you who aren't too good at subtraction, that brings the price down to $39.99, the same cost as the online upgrade price for current users of previous Windows versions.
