Wow, it was only released the other week and already I've got an email from Amazon.ca that Twilight is available to order for $24.49. I don't know if this link will work for everyone - but here's what I got from my email:
Availability: This title has not yet been released. You may pre-order it now and we will deliver it to you when it arrives. Ships from and sold by Amazon.ca.
I wonder how many 'editions' of the movie are going to be released? I'm betting there's definitely going to be a box set. They're totally going to cash in with this... and I'm betting I'm going to buy all of them lol
