Summit has free shipping to Canada

If shipped by FedEx, I believe you will get hit with a customs processing fee
No, because everytime I have ordered from summit and shipped to my home address in canada Summit has collected the tax at the time of purchase.
The odd time the part comes from Ohio the package does not seem to get hung up at customs. As long as the tax is collected at time of purchase then there will be no brokerage fees.

Majority of the time the parts seem to ship from Mississauga
