From Asia, usually they will ship via regular parcel services. As far as I can remember, anything under CAD20 they will not charge tariffs. From the States, I have the same experience with fibbi, never go through UPS & Fedex... Their brokerage fees are outrageous. Sometime it's way higher than the postage itself.
Buying local is good but not too much choices and most of the model are outdated. So that's why I prefer to buy from ebay etc. Canada is not a shopping paradise like HK anyway.
Why don't you ask the seller declare lower value? You don't need to pay any taxes at all as long as the parcel is under $50-60 (not really sure). But you can check it in Canadian Custom website.
