[quote name='crunchewy']If I were you I'd call back and have them verify that it is more than just a cable (i.e. is the power brick too), and really is for the slim PS2. I'm guessing that is a fat PS2 power cord.[/quote]
Yeah, I got a feeling that it's a power cord for a fat one too. Those are around that price, while the slim ones(the ones with a power brick) are about $12.99 used and that's 3rd party. Although it could've been someone that entered it wrong into the system.
