WOW Amazon is offering Microsoft Windows 8 Pro for $54.99 (down from $199.99) and it comes with a free $25 Amazon credit. That is like paying only $29.99 for an upgrade to Windows 8. That is insanely cheap!
Qualified customers will receive an email notifying them within 10 days that the credit has been applied to their account, no coupon code required.
I would hurry, I doubt these will last long!
