If you have ripped your CD tracks into iTunes and have no further use for the disks, consider trading them for an iPod. I don’t known anyone who has used this service yet, but Millennium Music offers to give you an iPod (a different model depending on how many CDs) if you ship your CDs to their South Carolina location. Disks have to be in saleable condition with jewel cases and original artwork. They are essentially valuing your CDs at a little more than $2 apiece, e.g. giving you a 1 GB Shuffle worth $149 for 65 disks or a 60 GB iPod worth #399 for 175 disks. As I recall from my days of culling my collection and carting the surplus around to used CD stores, this is in the ballpark of what one used to get in that way. Big open question is how they assess the quality of your discs in crediting you.
