I have heard that if you have things sent as a gift valued at under $20CAD (or a test sample with no commercial value) then it doesn't cost you any thing. Good luck getting a computer store to ship from US with that method tho. If you have american friends who will buy you newegg refurb mobos on the other hand, it works out fairly well (or so I've heard)
You are in Quebec though; don't they actually LIKE paying taxes over there?
