I'd concur with the previous posts about CC and TD being bricks and mortar store options. Service isn't the best at CC but you're looking for deals right? NCIX is based out of Vancouver but good for cross-referencing pricing. http://www.ncix.com/search/index.php?quicksearch=matrox&minprice=Min.+Price&maxprice=Max.+Price
CC fine if you know exactly what you want. Don't go there expecting to have a salesman spend time designing your system with you.
