Rated 5 out of 5 stars
Not sure how I "survived" on-line shopping before Invisible Hand. It works unobtrusively, accurately and quickly. I buy most things on-line, and spend lots of time comparison shopping, so Invisible Hand is JUST what I would have designed if I could do it myself. I will keep using this and recommend it to everyone. Just another reason to always use Firefox--my only browser.This review is for a previous version of the add-on (188.8.131.52-signed).
