Been using tigerdirect.ca for 3 years , no duties or extra taxes . Ncix and directcanada are in British Colombia , all I pay is 6%gst when I order from them(I'm in Quebec). If you're in BC you need to pay another tax I think if you buy from them. PST

What I hate with directcanada is the way to browse items is not that good ( for example I wanted to buy a usb a /usb b cable , they have all cables in 1 category (cables) , so you need to go through all the items to find the one. And what I hate with NCIX is they don't always have item description so you need to google it.
