All perfect examples why I NEVER.........EVER........use ebay! Or ship things by USPS.
Always UPS or FEDEX. They are just as cheap or better than USPS "black hole" shipping. I have NEVER lost anything with UPS or FEDEX. I HAVE lost several thing with USPS. Once you give it to the PO, it is gone! Possibly forever lost.
Lesson learned?
