A sub section specifically for Canadians would be useful. USPS is a great provider but Fed Ex, UPS and Purolator levy brokerage fees at the border. Payment can be a little different and exchange rates are currently hindering purchases from South to North. A sub section for Canadians may generate some traffic.

I acknowledge that with less population and that I don't know if there really would be enough transactions to justify a sub section. Just a thought!
