It isn't any cheaper sending within Canada either. I sent from Vancouver a 20" mail tube to Toronto via express mail. It cost 19.00 Canadian and arrived in four business days, the same tube in the US sent priority would cost ~ 4.85 USD and 9 out of 10 times it would be there in two days. I wonder if the cost of sending mail in Canada is the reason that there are not more services like netflicks.
FWIW the postal delivery guys here in Van and earlier in Richmond were very personable folks.
