Invisible Hand is a really useful tool if you tend to do lots of online shopping yet too lazy to compare the prices between competing online retailers. Invisible Hand shows a discreet notification (yellow bar, image above) when the product you’re browsing or searching (google, yahoo, msn) can be bought for a lower price elsewhere. It gives you a link directly to the product page at the competing retailer.
I find this simple too very useful when it comes to comparing prices between inkjet cartridges, printer, laptop, digital camera and more.
- It stays out of your way – InvisibleHand remains invisible until it finds a deal on a product you’re shopping for.
- Real-time prices – Unlike price comparison sites, InvisibleHand refreshes its prices every single time you use it.
- It works with Google – When you google a product, InvisibleHand will automatically show the lowest real-time prices.
- Reveal hidden prices – InvisibleHand knows the price even when the retailer tries to hide it (US only).
- It learns as you use it – InvisibleHand will search for deals, even when you browse a product it hasn’t seen before.

For those using IE, Safari and Opera, bad news, InvisibleHand is only available as a Firefox and Chrome extension. I believe it is a matter of time before they release compatible plugins for other browsers. Here are some facts at the time of writing:
- Currently tracking 115 Retailers
- Total savings is $26,569,786
- Average saving $9.78
- 100% free
