I guess I'll be like everyone else and link to Froogle today. It's a good concept - just in time for Christmas too (though it doesn't appear that Google gets any sort of commission on sales). It doesn't really seem to work that well though; I wasn't able to find anything, or any better prices on things, that I wouldn't have been able to find just searching amazon, mysimon, bn.com, or whatever. I'm much more impressed with Google Catalogs and Amazon Light.
