I figure everyone must use Froogle by now, but in case you don’t here is the scoop. As a tool and product junkie I can’t live without it. It’s simply the first (and usually the only) place to go to find out where to get hold of anything sold. Rather than winnow through web pages refering to some product, use Froogle to select only sites that are actually selling the thing. Simple, powerful, brilliant. It’s Google’s better half.
[In 2007, Froogle was renamed "Google Product Search".]
