Which engine is better according to Mossberg?
Our tests yielded a clear winner: Cairo. In almost every case, its search results were better and more accurate than ShopLocal's, and it offered personalization and special features that ShopLocal couldn't match...Overall, Cairo is a smart Web site that makes it easy to compare prices at retail stores, and its added features that do some extra legwork for you take the hassle out of finding good sales. Until ShopLocal.com steps up and adds more personalization and accurate search results, the better Web site for deal comparisons is Cairo.com.
