Same items from amazon.ca comes to 122$+tax. Amazon.ca may be cheaper for us if we buy at regular price but it seems that DD's sales are still a good deal for us. Except for "The Sea Inside" which was at regular price, all movies were under 10$ when they're all at around 15$ on Amazon except one.
The bottom line is even though our dollar is at par with the USD, we're still paying prices like when it was worth 85 cents.
