Yeah, and if CKTG has them in stock already, there's a good chance they ordered their stock at a good wholesale price, and when the Yen was quite a bit lower (although I see that the Canadian dollar has surged against the yen -- about 3% -- since I did my CAD/JPY cash forex in Singapore last Friday). Grrr.
FWIW, I don't believe there are import duties on many made-in-Japan products entering Canada (tariffs on certain categories of goods are a different story), but what we really save with our Customs exemption is the sales taxes, which are really high in Canada. In Quebec, for example, we pay the Fed GST (5%) as well as the piggy-backed Provincial sales tax (9.5%), which adds 14.975% to anything you buy here, or import. For all intents and purposes, "duty free" for most Canadians means "sales tax free."
