Rated 5 out of 5 stars

I LOVE this add-on. Installed and have been using it for about a month now. Very simple installation, took less than one minute. Very clean and simple interface -- drop down only appears when I am shopping for items that are available elsewhere more cheaply. I immediately can determine if I've got the best deal, and with one click of the drop down find out about prices at tons of other stores. And when I'm done shopping, the drop-down goes away on it's own. I've already saved 20-30% on several online purchases that I would not have expected to find more cheaply elsewhere.

This review is for a previous version of the add-on (0.51).
