A couple of examples come to mind. An order came in over the phone during the weekend our postal expert was off duty. Another time I tried send some sci-fi titles to Poland. I don't even think I have enough web site space to begin to explain bureaucratic regulation I and the customer has to comply with to send a package to Poland, a supposedly free country. The government there feels they must make sure that custom officials do not let any anti-government material into the country.
Censorship is a sin.
So sayeth the 13th commandment. I think there was even some sort of permit fee. It was almost funny. Just for giggles call your local UPS and ask them what it takes to send a 5 pound package of books to Warsaw. If you do not get mysteriously disconnected, you will be amazed.
