Disappointing. Only seems to work on Amazon. Rated 2 out of 5 stars

If you are going to have a shopping toolbar, it needs to work on more than just Amazon. I checked several retailers (Bestbuy, Newegg, Buy.com) and it didn't work on any of them. There are plenty of other shopping toolbars that have way better coverage than this, and if you want price comparison with reviews, then InvisibleHand does a way better job than this.

This review is for a previous version of the add-on (1.2.663.1-signed).
