Quite a story! My lone comment would be - if you don't want to ship to Canada, then don't take people's money and agree to do so.
I've never ordered from her nor do I have an axe to grind,but I suggest you look at this Garden Watchdog page, especially the section dated January 11, 2010, and examine it for parallels to your own experience.
It's a great site to post your own impressions and people do check it too.
