A fellow computer friend introduced me to a little web tool last week that I thought was pretty cool. It’s called Invisible Hand and it works as an add-on in my Firefox browser. It helps you save money when shopping online and that’s always cool.
When you have the add-on installed and you visit a website or webpage that is a product page for an item, the Invisible Hand kicks in and searches other websites behind the scenes and then lets you know if you could save money by purchasing the item on one of the other sites.
As you can see from the screen shot above, I was looking for a Zune 120GB device on Amazon’s website. The Invisible Hand add-on fired off a status bar at the top of my browser window and let me know I could save $50 if I purchased the device at Geeks.com.
I can click on the button for the site with the lowest price and be taken immediately to the product page for the item on that site.
The only real challenge I see with the tool is that it doesn’t take into account any shipping charges that may be different between sites and in the case above, the product was currently out of stock on the cheaper website.
Perhaps these are improvements that can be incorporated in future releases of the Invisible Hand add-on.
