Los Angeles-based PriceGrabber.com said this morning that it has entered into a strategic alliance with MSN. PriceGrabber's comparison shopping services will be included on MSN Shopping, and included in a wide range of MSN shopping categories. PriceGrabber provides price comparisons, deal information, and offers for online merchants. The company's web site provides information on the retailers offering items for sale, a comparison of their costs and shipping, and allows customers to click into buy products. The PriceGrabber site is similar to Shopzilla, which was acquired by E.W. Scripps last week.
