I live in Edmonton, AB. Have bought and sold via this site. You can occasionally find worthwhile deals for buying (once you take customs fees/gst into account). I almost never ship by UPS/FEDEX ground (they charge astronomical "processing" fees.
The Canadians that visit the site
It would be helpful to know who else lives in the Great White North, certainly make buying/selling/trading gear a little easier without worrying about our good friends at Canadian customs trying to take more hard earned money from us. I'm in Montreal, email addy is jefflo@istar.ca
