This is a great site. It's a good way to get rid of your cds that you no longer listen to, and get some in return that you want. They tell you to wrap your cds in a piece of paper to send, but when I did that the person who received it said the cd had broken during shipping. So after that I sent all cds in the cd case inside a bubble mailer. It was a few dollars more for shipping but that's the way I would want them sent to me.
If you really want to get rid of your cds I suggest giving them to Goodwill because that is truly free.
