PC-Canada is usualy the place where I find the cheapest deals for the electronic stuff I buy online. Their service is good and they ship quite fast providing tracking numbers. Their website could be improved because many products do not have photos attached to it. Be careful not to open packages brfore making sure it is really what you need because you could have trouble getting a replacement or a refund.
