Why are books 20% more expensive in Canada than in the US? I bought a book today and it listed 2 prices (as most books here do), the book is $14.95USD compared to $21.00CAD. When you account for the currency difference it's a 20% premium north of the border. So why do I have to pay so much more for a book than Americans?

Update: Apparently I'm not the only one complaining, I found this article from the Globe which states that prices were suppose to go down in July, guess they need to come down again.
