For a long time now I’ve been preaching the benefits of the Firefox web browser for a few reasons, because I am a huge nerd. My favorite reason for using Firefox is the third party plugins that add a lot of functionality beyond standard browsing.
I’ve always said if you’re buying anything but music, DVDs or appliances from Best Buy, you’re probably getting ripped off. Fortunately Invisible Hand is a plugin for Firefox that allows real time shopping comparisons for products on major shopping websites, including Best Buy. If there is an identical product with a better price on another shopping site, a little notification will tell you, “Go buy it elsewhere.”
So now you can go stimulate the economy and do it prudently thanks to Adam Smith’s metaphor, now in Firefox plugin form.
