I've been a member of the APS for five years. The American Philatelist is mailed to me, each month, in a plastic bag. The postal sticker on the bag usually says
Canada Post. The magazine is printed in the U.S. and trucked to Windsor, Ontario.
Canada Post gets paid for delivering the magazine to me.
This month's issue shows it was posted in SWITZERLAND! How did the magazine get from the U.S. to Switzerland?
