Rated 5 out of 5 stars

I found this in extension Google Chrome first. I liked it so much I added it to my Firefox. Has saved me quite a bit of money so far, without me needing to think about it. @river_dacota I prefer the alert style easier to notice (for me).

This review is for a previous version of the add-on (1.4).
