My time, plus fuel used plus wear and tear on the vehicle, is worth more to me than the $100 or so I will spend on shipping. Remember, you still have to clear Canadian customs when you are returning from the US. You will pay customs fees regardless.

That's where we differ then. I don't mind the road trip plus normally I am picking up multiple items. So more savings. The wear and tear doesn't bother me either my cars are here to be driven and I drive them hard! There's a reason I am on my 4th set of rear tires on my Z.

As for customs. Just tell them what you want, that is between you and the officer. But honestly I have not had to pay duties on lots of parts. Just depends on the officer and or what you tell them. Most time I have been able to say it was used parts. Or tell them your bringing parts back into the country from a big Z meet. I tell them they were my parts I brought down and was trying to sell at the meet and these are what's left, couldn't t sell etc. They normally just wave me through.

O also when a shipping company brings packages cross boarder for you they like to charge you up the assssss for duty fees or brokerage fees on top of the duties.

That's a good thing, that we all differ. Life wouldn't be as interesting if we were all the same. I work for a large US based firm with branch offices all over the world. I travel often and I would not take a chance by not declaring any purchases made in the US. It takes just one time to get caught and black listed on the Canadian and US database and you are screwed in more ways than you could figure on. Better to pay a bit more and have peace of mind than wondering if I will be allowed to enter the US or have a deep cavity search performed the next time I am crossing back into Canada. No way, no how!
