Yahoo has now sold Kelkoo to a UK-based private-equity firm called Jamplant, TechCrunch reports. According to Wikipedia, Kelkoo has been profitable since the fourth quarter of 2002. The entry says:

On the site itself, it differs from the Google Product Search and PriceRunner model in that it allows retailers to bid for placement in search results. It also covers more categories than most competitors, including clothes, travel, electronics, and auctions from eBay.

In addition to being a price comparison site, Kelkoo is also one of the content providers for SmartShopper.com browser add-on.

That probably made the deal a bit more attractive to the buyer, but the price was probably more attractive. Speculation about the site’s sale has been going on for a while, and according to TechCrunch, sources with knowledge of the deal say Jamplant got it for "something less than €100 million."
