Amazon is at it
Amazon is the same.
I purchased a copy of Windows 7 Ultimate for £79 thinking it was dirt cheap and there must be a catch but it was Amazon so I purchased it. The software activated and got updates for 2 months then I was hit by the "Windows is not genuine" message at the bottom right corner.
Turned out I was sold an MSDN serial key which was later flagged by Microsoft.
It happened to numerous other people who were complaining in the review section of the product. Because it was 2 months after purchase, it was difficult to get refunded but I did in the end as the reseller was not replying to my emails.
Just looking at Amazon now and it looks like they are still allowing these scammers to sell their pirated software through Amazon.
