The best thing to do in this situation is to establish contact with the buyer. There are many reasons why a buyer may have two different addresses, and it’s best you clarify with the buyer which address he or she wishes to use.
If you are unable to reach the buyer, use your best discretion as to what is best for the situation. If you choose to cancel the order as Item Not Available, send us a support request so we can remove the option for the buyer to leave you feedback. If you do wish to send the item, note that PayPal will only offer you financial protection as a seller if you have sent the item to the address registered on the buyer’s PayPal address. For this reason, we often advise sellers to send the package to the address listed in PayPal.
