Trading books, DVDs, CDs...

Here's this good site that's popped up. Zunafish is a trading site where you can trade in your CDs, DVDs, VHS, books, etc. for others that people want to get rid of. Got an old copy of 'Jurassic Park' that you don't care to watch again? Maybe you can trade it for a copy of the 'Da Vinci code' that someone's read but doesn't want anymore!
It borrows the concept of ebay, and extends it to a craigslist-like community board - formalizing it into clearly defined OTC trades.
It'll be interesting to see how it works out.
