I just discovered something interesting... wondering if I'm missing something,
or whether I'd get blasted unexpectedly (if I hit the buy button)

Thanks to Dashielle, I started cruising around thier website, and thought I'd investigate actually ordering somehting (best way to get the bad news is to pretend and go through the process). I discovered:
1. When I converted the currency from US$ to Can$, the prices didn't change.
2. There doesn't appear to be any duty.

This has of course put the temptation factor WAAAAAY up.
