Excellent point. I have experienced the same thing. I now use only USPS (US Postal Service) or FedEx when shipping to Canada if possible. I don't see how UPS are getting away with these excessive brokerage fees when no other carrier does.
To Canada, I find that USPS express mail from the US is fast and at a reasonable price - with no brokerage fees.
I'll have to look into this class action suit.
