My surface mail to Canada and America went off in time for the last surface mail posting date in mid October 2016.
The packages would take minimum four weeks and a maximum of five weeks to arrive, said the post office clerk.
The stated timing was perfect; early slow mailing is economic and in any case, there was plenty of time for slow delivery. The packages could have taken six weeks to arrive and still been in time.
Five days after posting, I received my first thank you email for my gift. It was soon followed up by a second one……………. Ships, coach and horses, obviously sprout wings.
