Sorry if there was any confusion, the example we listed was to outline that we can box up and try to provide a better shipping quote than the computer generated API, that Canada post provides when you allow Irunguns to enter manual shipping dimensions.
the box for your order is a 16x12x4 with a weight of 8.8 lbs, if you go to Canada post web page and enter the dimensions and weight we listed, you can see that the rate is the same as what we offered in your order. Let me know if this clears things up.
