Rest easy at night and get delivery confirmation when you ship your valuable items. A small percentage of buyers will receive an item and say they didn't get it and demand a refund.
You can cover the cost of delivery confirmation in your shipping charge. It only costs an extra 35 cents.
You can email the tracking number to the customer so they can track the package.
ALSO, it protects the payment you received via Paypal. For, if the customer claims never to have received the package and you have a tracking number proving it was delivered, Paypal will rule in your favor.
