Registered Mail often takes way too long to get delivered. If a buyer opens a case just one week after he paid, Ebay will force a refund three days later, so the buyer will get his money back and a free item at your expense.
For example, we recently sent a Registered envelope to a customer just 15 miles away. It took nearly five months for USPS to make its first delivery attempt!
Also, USPS insurance is a joke for Ebay purchases because it requires buyers to provide a copy of the actual financial transaction with the buyer's bank replete with his account number, which most buyers will not furnish due to privacy concerns. Even when they do, the USPS claims process is extremely tedious, time consuming, and frustrating. USPS will require you to jump through many laborious hoops by filling out absurdly complicated forms yet will find excuses not to pay even when you did everything properly.
If you are lucky, USPS will pay a claim but only after you have spent perhaps 15 hours dealing with their bureaucratic nonsense, including filing up to three appeals.
For me, it is always Priority or Express Mail with private insurance. You have been warned.
