My rule of thumb is, if you have to ask "is this a scam?", then it almost certainly is. A link would be good, as we could really look at it then.
I did see something recently on BoingBoing.com (can't locate it now) about an auction for a PowerMac quad G5 that closed at well over $1000, and the listing was titled something like
PowerMac Quad G5 with Studio Display! NEW! List and the page long sales spiel about how great the PowerMac was ended with the words "This auction is for a list of suppliers who can provide you with a PowerMac at massively discounted prices."
So, in essence, some poor sucker paid over $1000 for a piece of paper advising them of where they can buy a PowerMac. I think its currently under review by eBay and the courts, but it'll be a while before the buyers get their $$$ back.
EDIT: while hunting, I found this:

Ha ha ha! Some people will try anything. Thats tantamount to walking up to someone in the street and muttering really quickly "If you say what then you agree to give me your wallet.", stealing their wallet, and expecting to be able to use that as a defense later in court.
And this one is great:

He he - an Air Guitar. Nice!
And I finally found the article. Wow, my memory of it was way off. It was $51 paid for the list for an LCD monitor.
