I don't know if America proper gets better rates, but my shipping prices to Canada make my wallet cry. This was direct from my Receipt for the CE of Final Fantasy Explorers for 3DS:

Subtotal: $69.99
Shipping: $33.99
Taxes: $0.00
Total (incl. taxes): $103.98

And that's in US dollars. I ended up paying $151.05 in Canadian dollars for a 3DS game.
