Invisible Hand has saved us thousands of dollars over the past four or five years. It's wonderful to have a single tool for comparison shopping in North America and Britain. I particularly appreciate the folks at Invisible Hand ensuring updates are offered so that it evolves along with Firefox. I can't imagine living, or shopping, without Firefox and Invisible Hand.This review is for a previous version of the add-on (3.6.8). This user has a previous review of this add-on.
Invisible Hand is easily the best comparison price tool for Amazon US and UK. I constantly use it to determine whether somewhere else has a better price. Great Add-on. ThanksThis review is for a previous version of the add-on (3.6.8).
