Shipping to Canada. Question for you folks up north

I live close to the border and always have my items shipped to the Ogdensburg UPS, then pickup myself. Even counting gas, bridge tolls and Customs charges it always costs much less than trying to buy in Canada. This is especially true for speed or specialty parts where buying in Canada is probably way more (double or triple $$$). Oh and if I do try and have something shipped directly to me I can usually more than triple the shipping time.
