AOL is planning on rolling out a comparison shopping engine – In-Store.com, which may be competing with Google’s Froogle or Yahoo Shopping. The New York Times reported that In-Store has been in planning for 18 months by AOL and the company is expected to start a large advertising blitz next week just as shoppers begin thinking about buying for the holidays. AOL is rumored to be working on a PPC based sponsorship/inclusion model similar to MySimon or Shopping.com.
