I think Ziffit are a great company to send your old cds, dvds and books too. They offer a high value for cds much better than other companies. Customer service are really friendly and reply back to you quickly if you have any questions or concerns. Their delivery service was brilliant and arrived on time and my money arrived in my account a few days after. My only slight criticism was as I had two boxes to send, the delivery man said they may end up in different locations, which had me worried, but everything went fine. I definitely recommend using Ziffit and I will continue to in the near future
