Most products including those made in Canada are cheaper in the US because of the sheer population over their. Heck even skidoo made by bombardier in Quebec is cheaper in the states. Shipping is free and selection is much better. Just compare amazon and costco on both sides of the border to see for yourself.

I got my 6 -40 military modular sleeping bags from tonystactical.com
50lbs of huskless oats from a farmer. TSC has 50lbs baking soda for animals ( good for cleaning)

Tell me about your great deals that were shipped at a great deal to canada
