The package that I sent to the buyer a few days ago will be returned to me because the buyer's address on paypal is not correct. The buyer asked me to send it again to her and is willing to pay for extra shipping fee, my question is to be eligible for seller protection, how can I accept the extra shipping fee and send the package again? I want to use paypal to print shipping label, do I need to refund her and then send a new invoice? Is there any simple way to do it? Thanks in advance!
