Google released a handy update to "Shopping Buddy" (previously Google Checkout Promo Notifier) extension for Google Chrome that brings discounts plus ratings right into your browser. The extension now displays merchant ratings and reviews, so you can find promotions and learn more about a merchant all without leaving the site you're shopping on.
The seller rating will display as a star with score from 1 (lowest) to 5 (highest) in the URL bar. To read detailed reviews and see the distribution of ratings, just click on the star.
