I was searching for a copy of Windows 7, and I came across this site: http://www.msoftkey.com/
They advertise selling a copy of Windows 7 on a USB key for as little as 20 dollars. Ultimate edition is 32 dollars. Anyone know if this is a legitimate website?
I tried chatting with one of their representatives, and their explanation of the low price was that they buy they keys in bulk and pass the savings along.
