Not sure where you live in relation to the border, but since you can walk into a shop and simple buy it over the counter and bring it back yourself, that may be a easier way to do it. I cross the border all the time and it's easy to do any paperwork if you know what you need. Since you would have to "TEACH" the us shipper about what paperwork you need them to fill out and how to do it, you would already be the expert.
