I wonder where they came from:

These will be genuine keys being illegally sold, with professional counterfeit packaging I think. I mean, just look how genuine it looks!!!!

Many will think they are running the real thing. Lots of these being drop shipped on ebay at the moment. Some from sellers with 100% positive feedback or using hacked accounts. A few who've bought them seem happy - of course M$ might de-activate at anytime or not at all. The risk you take....
