Google Has a Shopping Utility Called Google Shopper

Shopping with your phone is nothing new. As soon we got browsers on our smart phones, we were searching for products we saw in-store, hoping to find better prices. Over the years, these applications have gotten more sophisticated. 3D-bar code readers use your cell-phones' camera phone to literally scan bar codes and search for products. There have also been products that let you photograph products and search for matching objects online. There's even voice search.
