When selling CDs, it can be a big advantage to offer to post the CDs and their paper inserts without their CD cases. This will drop the postage cost dramatically , especially if you are posting overseas, postage for many overseas countries is getting ridiculously expensive. The buyer can buy replacement CD cases much cheaper than paying postage for the CD case.
It is important to let buyers know that the CDs will still be well packaged All they need is some bubble wrap around them with a a thin piece of cardboard
Sending CDs without the cases can decrease the postal costs by up to 50%, encouraging buyers to bid higher and more often.
