After a heated debate with MS UK I have removed this post. Nobody bought any from here, or reported this post. I had a listing removed from Ebay and that made me look at why:
It seems that the sale of a brand name (ie HP, Compaq etc) master/recovery disk is a breach of intellectual property rights, unless it is sold along with a PC made by them. Rather a bizarre bit of legal junk, but none the less it is there. Even though I have access to, and the ability to sell them as a package with the pc, it just isn't worth bothering over the net. I guess it's down to local sales of the Disks and PC together.
This may help as a warning to others thinking they can legally sell the old disks from their OEM PC's.
PS: Anybody want to buy a copy of "The Road Ahead" by Bill Gates. This will teach you how to dream up these rules and cash in LOL .
Thanks again to Doug for letting me post this advert, but on reflection it is better if I remove it
