Please note that Microsoft insists that all product keys technically be sold with hardware included. They will cancel ebay listings if there is no hardware. You can't argue with it, it just happens.  So, then, this auction includes one old dead hard drive.  If you buy this key, then the hard drive is yours! If you want me to ship you your hard drive, just send a note, and I will raise the shipping costs accordingly.  If you don't want your dead hard drive, just do nothing and you'll get the book you wanted and I'll throw your dead hard drive away.
