Westlake Village, CA – November 1, 2005 PriceRunner (www.pricerunner.com), the comparison shopping site owned by parent company ValueClick, Inc. (Nasdaq: VCLK), today announced that it ranked highest in PC World’s rating of top comparison shopping sites. Editors praised PriceRunner for its usability and the excellent deals it delivers to shoppers. Launched in the US market in July of 2005, PriceRunner’s rapid success in the competitive comparison shopping arena highlights the company’s ability to deliver what the consumer wants.

With more than 5.5 million readers, PC World is a definitive source of computer and business information for technology buyers and users. The PC World Rating is the overall rating for a product, determined by independent review from the PC World editorial staff and resulting from the combined scores of four major component characteristics: features, performance, design/usability, and price. PriceRunner and its competitors were tested for real-world results of searches for three different consumer products as well as each site’s organization, interface and extras. From a pool of 20 companies in the comparison shopping arena, PriceRunner was honored with the highest overall rating.

“At PriceRunner we’re firmly committed to delivering a comparison shopping site that’s best for the consumer,” says Martin Andersen, General Manager of PriceRunner, US. “Ease of use, functionality, unbiased presentation, consumer choice, and ultimately the best deals on what shoppers want – these are our priorities, and so it is a pleasure to be recognized by PC World for delivering on that PriceRunner vision.”

According to PC World, PriceRunner found the lowest bottom-line prices on all three test products, and its helpful sort and filter options offer users targeted search results. The editors noted that PriceRunner’s unique online/offline pricing offering, which means that in-store prices make it into the mix, is a key differentiator from the competition. In addition, PriceRunner always lists the lowest priced retailer first, a consumer-friendly policy that stands in stark contrast to its comparison-shopping competitors, which typically incorporate advertising dollars into the rank.
