Also, if I might add, you can purchase pre-paid registered envelopes that you tear off the slip and retain

the tracking number and they can be posted in an ordinary mail box.  You don't even have to take them to the PO


You can do that and they may get to their destination ok.  However the terms and conditions of registered post exclude the $100 compensation if registered post articles are not lodged over the counter. In addition, you would not have proof of addressee nor proof of post for paypal seller protection - unless article was scanned along the way.
