Just thought i would post this tidbit of info for those who got an email to get win 8 for 39.99. When going through the checkout process you will see a box to enter a promo code. Go to this site "https://www.windowsupgradeoffer.com/" and fill in your info to get a code that will give you 25 bucks off Windows 8 Pro. I mean for 16 bucks you can't go wrong if you don't care for it.
Just a note, when you enter the info on your recent qualifying computer purchase
remember to enter any date after June 2, 2012.
