Today Yahoo released its new and improved shopping site, complete with comparative shopping. A search for a Sony Cyber-shot camera on Yahoo yielded 89 merchants and a PriceGrabber search found 69 results. Lowest final price on Yahoo was $520 compared to PriceGrabber’s $598, a 15% savings. Does this make PriceGrabber a prime takeover target? Yahoo and Google now have their own comparison service. PriceGrabber provides Ask Jeeves with a cobrand. AOL and MSN have the cash to spend.
