However, if you aren’t ready to jump to Windows 8, you should at least make the purchase and create a DVD or USB installation media, which will allow you to install the operating system at a later time. This is definitely an offer you shouldn’t let it get away, because after Thursday you’ll have to pay full price for Windows 8 Pro upgrade, which currently is $199.99 (but if you shop around, you just might be able to get it for a lower price) and $119.99 for Windows 8 (core) edition. Now, if you are a student, this is a different story, because several weeks ago Microsoft started a program that allows students in the U.S. (and many countries becoming available pretty soon) to get the upgrade version of Windows 8 Pro for $69.99, still not $14.99, but it’s a lot better than paying $199.99.
