FYI, I processed a request form and received a set up upgrade disks in 2009 when the actual program was in effect. It was for an R500 with Vista that I had purchased. The disks were typical Lenovo disks with high quality black printing and a Windows 7 COA was included on the disk sleeve.
While the disks from the online sellers may work, they are almost definitely not from Lenovo or Microsoft, and are probably bootleg. The disks that I have seen are printed on white disks with a low quality color printer, judging by the smudging (that rhymes!) Assuming the product keys are unique, they may have been from key generation software or elsewhere. The disks do not seem right and Microsoft does not release software like this without the COA's.
Without question, the upgrade qualification period is over. That program required a new ThinkPad purchase of specific models with specific OS's between specific dates. Manufacturers used this as an incentive to keep sales going as people like to wait for new OS releases.
Generally, when something seems to be to good to be true, it is. Like $40 for Windows 7 Professional!

How does the Windows 7 Upgrade Option work?
The Windows 7 Upgrade Option is available through participating PC manufacturers on selected PCs and through Microsoft on qualifying purchases of the Windows Vista packaged product. The Windows 7 Upgrade Option applies to Windows Vista Home Premium, Business, and Ultimate editions. Your Windows 7 upgrade will be to the comparable version: so you'll get either Windows 7 Home Premium, Windows 7 Professional (the upgrade to Windows Vista Business), or Windows 7 Ultimate, respectively. The Windows 7 Upgrade Option program runs from June 26, 2009 through January 31, 2010. Individual manufacturers may choose to offer the option for a shorter period on their PCs. Offer details, prices, and upgrade delivery methods will vary. For details for new PC purchases, please check the manufacturer's web site.
What is the Windows 7 Upgrade Option program?
Specifically designated PCs that are pre-installed with Windows Vista Home Premium, Windows Vista Business, or Windows Vista Ultimate may qualify for an upgrade to the equivalent Windows 7 product. Similarly, in some markets, retail packaged Windows Vista software products (sold separately from PCs) may also qualify for an upgrade to the equivalent Windows 7 product. The upgrades will be provided to qualifying customers when the Windows 7 product becomes available in the market (also known as "Windows 7 General Availability").
