I found a site once that had a ridiculous price for an ultimate key, I contacted Microsoft's fraud department and asked if the site was legit, got a reply back saying they'd check into it and then a day later a reply saying no problems, bought the license and saved the emails...
any chance you remember the site name?
I'm on my mobile right now but I'll look through my emails later today...
With an .edu email address you can get a free version of win2k8r2 server along with a ton of other Microsoft software from dream spark... I can sell you a valid .edu email that works with dream spark for 1 bitcoin
