Froogle now has merchant ratings. For example:
   http://froogle.google.com/froogle/merchratings?store=amazon

Interestingly, these are more of a meta-rating, aggregated from several sources, including bizrate, shopping.com, and pricegrabber.

Thanks Andy. I moved this to the front-page.

great. froogle was becoming unusable because of scam shops who were offering products for low prices just to come up first in the listing. Hopefully they will add more rating sites so that each item will have rating displayed on result pages
