That's why you ship USPS.
I got a $450 fee for someone who shipped turntables to Canada via UPS. If you refuse at the door to accept, and ask to get the customs cleared yourself - you can go the customs office (mine was near the airport) and clear it. Then you return the forms to UPS's office and they are obligated to give you the package.
It came down to $65, but it took a whole day.
