Rated 5 out of 5 stars

A fantastic add-on which saves me money on a regular basis. It's probably most useful for the everyday items - that are too cheap to for it to be worth your time to check competing prices; the add-on works quietly in the background and only appears when it discovers that the item you are looking at costs less on another site.

This review is for a previous version of the add-on (3.6.8).
