The Beer Prayer - Our lager, which art in barrels, hallowed be thy drink. Thy will be drunk, I will be drunk, at home as it is in the tavern. Give us this day our foamy head, and forgive us our spillage as we forgive those who spill against us. And lead us not to incarceration, but deliver us from hangovers. For thine is the beer, the bitter and the lager, for ever and ever. Barmen.

I never paid more than 50€ for windows products. They are usually reselled unused licences from an enterprise licence pool. As an example, I am the IT guy from the local school in my spare time, which we can see as a little company (50 laptops, 1 server, 2 xerox, ...) and we buy MS Office licences for new computers in the school. The microsoft volume licensing scheme delivers in our case usually up to 5 more licences than the bought amount with each purchase, that you may or may not use - do not ask me why. I won't go into details but due to public money and regulations and bla bla we HAVE to buy new licenses and cannot use these free ones. I could easily resell the unused licence keys because I will never be able to use it, and that is precisely what companies like the one you mentioned do.
I do not think it is entirely fully legal, but I do not think it is written anywhere that is not, so ...
Long ago, and with a different version, I had some trouble with a MS Windows license. As it turned out, I had a product that was validly installed via an OEM key that had since expired. It was later disabled by MS because it was being used 'fraudulently' . Also, it could only be used on OEM versions and OEM versions could only use OEM keys.
In my case, I had a valid MSDN key to reactivate it but it was rejected. There were all sorts of unpleasant problems, but only after it went bad and I needed to reactivate it.
