I find it very interesting that they consider shopping comparison sites low-quality. I remember seeing lots of bizrate, shopping.com, etc bidding on keywords. I agree with Google that these are really just arbitrage sites who are passing the traffic along to the merchants who advertise with them (at a premium). To me this seems like a great change which will benefit online retailers, who I am assuming (am I correct?) are AdWords' major customers. Shopping.com et all were just driving up bid prices and making it unprofitable to advertise.
