I am completely with you on ordering online, but only from Canada! Those duty charges can just kill you.
Anyway, I took a quick look and it looked like you could find it online at both amazon.ca and chaptersindigo.ca (I just googled chapters indigo - not the exact website).
The good thing is that with lots of DVD's and books, they're much cheaper online anyway than in the stores. And I know with books, if you need a few things and they add up to $39, the shipping is free. Not sure about the DVD's. I just bought a few books from Amazon and they were here in less than a week.
Good luck, hope it works out for you.
