Hey, have you checked out Listia? It's a new members-only site where everything is free and you can get some cool stuff without spending any money. You give away the things you no longer need, and get things you want for free.
It's all done using free credits instead of real money. Most people start with 100 credits, but this invitation gives you 150 to get more when you start. I'm already in and you can get started by clicking this special link: http://www.listia.com/signup/33672
