Where can I Purchase Granite on the internet?

Are there places on the internet where you can purchase Granite (http://tanbrown.org) for a reasonable cost. In our area it is outrageous and (http://maplered.com) we can't afford it. My husband (http://maplered.com) is considered to be one of the best wood craftsmen in our area so it shouldn't be too hard for him to install it with proper direction, ie your dvd's etc. Thanks
