The Business Insider has a source who claims that Amazon is in talks with Microsoft to be the partnered provider of shopping search results for Bing. The move comes after Microsoft announced they would shut down their “Cash Back” program on July 30th. The deal, as TBI puts it would give Amazon ownership of “the shopping results that are served up from Microsoft’s Bing search engine;” presumably, they would provide the top hits in the Shopping tab. No word on the monetary terms or timeline of the proposed deal.
