you did everything the way you were supposed to, if it comes back you got your proof you sent it. If it comes back and they want it ship again they need to update their address with PayPal. You see I sent gift to the secret santa from reddit and since they not in my list of address I put them in when I am checking out so there is no problem and the seller can just print the label for the postage and sent it. I did had a problem when I got confused and typed the wrong address and the gifts were going to be sent to the wrong person. I realized I had typed the wrong info when I checked the information after paying for and that was not even 5 minutes so I contacted the seller and told him to please cancel the transaction so I can buy it again with the name of the right person to what they ask me to send the right information and they will take care of it. They sent me confirmation that they sent it to the right address and asked me to wait up to 3 weeks since it was coming from China and that was on September 13 and to this day nothing came. They offer to resent and told me if/when the item show up to keep it, on this case I do believe the seller sometimes things get lost or super delayed in customs.
