Rated 5 out of 5 stars

I use PriceBlink all the time. Actually, I never have to "use" it, it's just there when I need it! And now they have shipping costs shown for lots of product and sites. Most of the time I just use it on Amazon and other big retailers to be sure I'm not overpaying, and even if the price is just a bit higher on the site I started with, then I go ahead and purchase b/c I trust them and already have an account set up.

This review is for a previous version of the add-on (1.1).
