Rated 5 out of 5 stars

Absolutely brilliant add-on. From the moment you install PriceBlink, you can tell a lot of thought was put into its development. Clean, fast, simple, straightforward. It does exactly what it's supposed to -- save you money -- with hardly any effort from the user. I used to spend uncontrollable amounts of time searching for low prices online, thinking I was being frugal, when I was probably wasting more time than I was saving money. But no longer am I searching and sorting through the various bargain shopping sites; PriceBlink does all the work for me, in a beautifully-simple toolbar that appears only when it's needed. In fact, it fits in so well, I forget it's an extension! And now I certainly can't imagine shopping online without it. Stick this one on the "must-have" list for any Firefox user.
