The easiest/cheapest/quickest route is to have someone in the US order one direct from a dealer using your VIN (so you get the correct part) and then have them ship it to you. I had to do this after some fantastic local broke into my car.
If you order through the base Autoport they'll mark up the price of the part 400% because, you know, they actually have to go on their computer and type things.
Don't be surprised if you have to go back 2-3 times after they repair it to have it "re-repaired". It was really confusing to me how I couldn't unlock my door after getting a window replaced, then once getting the lock repaired the window wouldn't roll up after being rolled down...my car is a 2009.
