InvisibleHand Review

InvisibleHand is a very useful add-on for Firefox that compares prices on products you are browsing for right in your browser window. You don’t need to go to a price comparison site, all you need to do is install it and when you browse for a product you are interested in, a notification appears on top of your browser window.

The add-on gathers pricing information from many popular online retailers such as Amazon, HMV, Dixons, Game, Play, Zavvi and many more. So, what’s the catch? Well apart from the developer getting a small commission from the retailer after clicking the link to the product, there is no catch. It won’t affect your price whatsoever.

Currently InvisibleHand only works with online retailers in the United States, United Kingdom and Germany, with Canada being supported soon. There is no word whether more countries will be added yet but you can recommend your country by sending them an e-mail.

There have been a couple of bugs that I have noticed. Most noticeably was when browsing for shoes it linked me to something totally different. This is a known issue and the developers are working on it. I found it is best when browsing for media such as games and DVDs. However, if the product you are looking at is a special edition or has some exclusive content bundled in, it doesn’t seem to compare prices with other sites.

Overall, if you shop online and find trawling through sites to get the best deal a chore, I would definitely recommend installing this add-on. It doesn’t affect browser performance in the testing I did and apart from the minor annoyances expressed above, I am quite happy with it. There is also an option for Chrome users to install the add-on, but I have not tested it out.
