Thank you for your research. I saw that, but the service would be arranged by me under my UPS account so I wasn't sure how much control the buyer would have.Gotcha:

"To be eligible for PayPal’s Seller Protection, you must meet all of the following requirements
- The primary address for your PayPal account must be in the United States [for U.S. accounts].
- The item must be a physical, tangible good that can be shipped.
- You must ship the item to the shipping address on the transaction details page in your PayPal account for the transaction. If you originally ship the item to the recipient's shipping address on the transaction details page but the item is later redirected to a different address, you will not be eligible for PayPal Seller Protection. We therefore recommend not using a shipping service that is arranged by the buyer, so that you will be able to provide valid proof of shipping and delivery.
- You must respond to PayPal's requests for documentation and other information in a timely manner as requested in our email correspondence with you or in our correspondence with you through the Resolution Center. If you do not respond to PayPal’s request for documentation and other information in the time requested, you may not be eligible for Seller Protection.
- If the sale involves pre-ordered or made-to-order goods, you must ship within the timeframe you specified in the listing. Otherwise, it is recommended that you ship all items within 7 days after receipt of payment."
I guess it's a UPS issue then to see if the shipper can specify that address changes are not allowed. I'm a UPS choice premium member and can reroute my packages to an intercept point, alternate address, or UPS store for no charge. This would apparently totally void any seller protection.
