does the post office charge for return to sender
The post office will not know anyway if the package was opened because they cannot confirm the condition the package was originally sent in. Once you write return to sender on the package and cross off your address you have to physically take it and hand it to a person at the post office. just had this happen and my Post Office said have the customer write REFUSED on it, do not open it and send it back. If they open it then they would have to pay for shipping. mang00se1 2:07 pm May 25, 2014 EDT edited. The package can be opened and still be returned to sender.
