Impulse purchase optimization...
Sprint Nextel Corp. today begins offering a mobile-search service from closely held GPShopper LLC that uses global-positioning-system technology, enabling consumers to use cellphones to find products in retail stores.
The service allows shoppers to learn where they can buy, say, a certain iPod model or new Nike sneaker, based on a location signal, and at what price.
Previously, users of the service, called Slifter, needed to punch in a ZIP code (which they still can do) along with product-search terms. Not knowing a ZIP code was a roadblock for people in unfamiliar locales.
