HeyBub:

You said in another thread that your Harbour Freight saw weighted over 50 pounds, but the shipping on it was only $6.99.

I had to pay $12 to ship three lithium ion batteries for my digital camera from Vancouver to Winnipeg. Those three batteries together weighed less than one pound. Maybe the distances involved account for the difference in shipping costs. Vancouver, BC is about 600 miles from Winnipeg. Was your saw shipped that far?

Was that the US Postal Service that did the shipping on the saw, or a courier like UPS or Purolator?

Obviously, something seems amiss when it costs less to ship a 50 pound saw than one pound of batteries. Either the shipping costs in the US are super cheap or the shipping costs in Canada are super expensive.
