well, you usually only have to pay taxes if the item is shipped from your state, but i'm getting an idea you live in canada and things are probably different there, eh?
yeah I need to know, because I want go to the Torontos Tigerdirect (8401 Woodbine Avenue, Markham, ON L3R 2P4, Canada) shop and buy computer parts, if I need to pay taxes (I think 15%) my computer will be a piece of krap...
