It will only fit in a Large Flat Rate Box. The cost via the Post Office is $33.95 - that's what we will charge you (our actual cost). FYI, the package weighs 14 pounds.
I understand your position about shipping being free to the US vs. charging to Canada. However, we ship in the US mostly via UPS and FedEx. Because of the volume we do with them, it costs us very, very little to ship packages within the Continental US. The Post Office doesn't give us a break, so we just can't offer free shipping to Canada.
That being said, our kit is less than half the price of the kit from Mopar Performance. There is still a BIG savings, even with the $33.95 shipping charge.
I hope this makes sense.
