If you are doing comparison shopping.
www.froogle.com is your friend, it will find you all the places that are selling the item that you are looking for.
The best thing about
www.overstock.com is their shipping price. Mostly everything ships for 2.95 or less, including furniture. Their stock is constantly changing too, one thing you really have to watch with them, is most of their electronics is refurbished. It says it clearly in the ad, but you have to look for it.
