jellyfish.pngMicrosoft has purchased comparison shopping company Jellyfish.com.

Madison, Wisconsin-based Jellyfish.com is a search engine that returns lists of rebated items from sellers, ranked according to price, showing buyers the full price of items including the rebate provided by the seller.

The company’s twist: When a buyer purchases something from a seller, Jellyfish.com shares at least half of the referral fee with the buyer that it makes from the seller.

Microsoft’s Live Search team blogs that Jellyfish.com’s technology may be put to use for shopping and commerce-related aspects of Live Search.

Terms of the deal were not disclosed. Jellyfish raised $5 million in funding from private equity funds Kegonsa Capital Partners and Clyde Street Investments last fall.
