While many companies have recently added business-to-business services to their product line, online shopping resource Bizrate.com Inc. Monday expanded with an acquisition that will increase its consumer services.

Terms of the deal were not disclosed.

The browser companion will be designed to travel with users as they window shop on the Web, providing access to a comprehensive suite of tools, including product reviews, price comparisons, special offers or discounts, merchant ratings and a digital wallet. BizRate.com's services will be included in the companion beginning this summer, the companies said.
