Shipping US to Canada by USPS

I'm Canadian but live in Michigan. I come back to the Georgetown area about once a month. You can have it shipped to my place if that helps and I will bring it back for you.
Take cwatts offer. I get parts sent to my shop lots, from the US. then at the end of the month I get my statement from the buying group, and its still a shock every time DUTY and BROKERAGE . For what? It's best if there is a drop of point just over the border and then go for a drive. We do this for stuff that there's no hurry for, and no extra mystery fees charges and cost involved.
