Has anyone tried Goozex -- the video game trading site?

I Trade sets a real world value for the game, and you buy "Tradebucks" $1 for 1 buck, send your bucks to who you want the game from, and if he accepts the trade, he ships it, and you release the bucks when you receive the game.

Each trade costs an additional buck, and the site is making money
easy
