I think Canadian consumers are being ripped off, particularly when it comes to high-tech products.
Let's take an example:
A Canon Powershot Digital Elph S400 goes for around C$650 at major Canadian retailers and webshops. Try London Drugs.
In Japan you can buy one for as little as C$460. Check out Kakaku, a Japanese comparative shopping site. If you can't read Japanese, take my word for it :-).
Does it really cost C$200 per unit to ship 'em over here? I doubt it.
