Some of my products display reviews and pricing in search. Some do not. It also depends on the search phrase...
Data point: Google knows your IP. Repeated searches from same IP may deliver results that are VERY different from another IP. Google also "knows" you. If it determines you are male, it may not display products targeted to women, etc... NOT just adwords.
It is difficult to test this as a "real" customer because google knows way too much about your browsing history and tries to serve content FOR you. In this case, google, please don't do me any favors, ok?
