ONLY THING YOU CAN DO IS IN THE FUTURE HAVE THE POST OFFICE EMPLOYEE SCAN EACH PACKAGE AND GIVE YOU A RECEIPT THAT WILL PROVE THAT YOU MAILED THE PACKAGE. IT WILL HAVE PACKAGE DELIVERY CONFIRMATION, DATE AND EXACT TIME THAT YOU GAVE THEM THE PACKAGE. IF ANOTHER BUYER CLAIMS THAT THE NEVER GOT THE ITEM AND THEY PAID YOU WITH PAYPAL, PAYPAL WILL REFUND THEM-NOT YOU.
