I really have a love hate relationship when it comes to selling CDs on Amazon. The love side of things revolves around the facts that CDs are generally cheap, they are small/light and you can find them everywhere. The hate parts come in with them being potentially scratched and the cases being broken. Fixing these issues just takes more time then I would like to devote to a single particular item. However, they can be very profitable. The video below shows some CDs I picked up at just one Salvation Army store!
