I'm fortunate enough to live right by Pt.Roberts, a tiny little U.S. enclave in Greater Vancouver. I had my box shipped there for $5. If you happen to live near the border I'd highly recommend this. You will save on shipping, will likely get it faster (it won't sit in Canadian customs), avoid duty altogether*, and return with a tank of cheap US gas.
*technically they can charge you duty but I guarantee the border crossings won't bother for such a small amount.
Doesn't everyone in Canada live near the US border?
