purchasing electronic stuffs in U.S

The first best way is to go with dealstobuy.com... it basically searches multiple stores like circuit city, staples, best buy, etc & displays the sorted results. Circuit city always gives one the best price. Similarly, there is another site called pricegrabber.com... pricegrabber lists re-furbished ones as well. There are stores like costo that give you even better deals. But, the issue is that they look for membership. It costs 100$ i believe. If you have any of your friends who are already having the costco membership, you surely will get a better deal that circuit city.
