Customers who purchased a Windows 7 PC from June 2012 through January 2013 have just two more days to submit their claims for a discounted copy of Windows 8, Microsoft said yesterday. From Computerworld:

The Windows Upgrade Offer -- a $14.99 copy of Windows 8 Pro to consumers who purchased Windows 7 systems between June 2, 2012, and Jan. 31, 2013 -- expires at the end of day Thursday, Feb. 28.

Microsoft emails qualified buyers a code that they then use to obtain the discounted price for a downloaded copy of Windows 8 Pro from Windows.com. Windows 8 Pro's current list price is $199.99.
