11.5 Items/transactions not eligible for PayPal Seller protection. The following are examples of items/transactions not eligible for PayPal Seller protection.

Items that are not shipped to the recipient's shipping address on the Transaction Details Page. 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.
