Not sure where you guys are from in Canada. I happen to live 30mins from Canada/US border so what I do is buy whatever offline and have it shipped to a "Ship-it Shop" that is just on the American side of the border, then I go pick it up and bring it across myself. This past month I bought 4 Bilstein shocks off ebay. It was free shipping to the continental USA or $125 shipped an extra 50kms to my door. Sometimes you have to pay duty but not always, depends on the mood of the customer guard.
Thanks. And I guess I am a bit late on the reply.
I am in Toronto. So, a 2 - 2.5 hour trip to the border. Not impossible.
Ofcouse, now that it is 2015 and our dollar is crap, it does not look like such a good deal. Should not have waited.
