Anybody have any ideas of where I can get product reviews to publish on a price comparison website.

It seems that so many websites share the reviews but where do you get them from e.g.
Acer d100 is a complete portable car navigation system that meets your mobile needs: easy, intuitive and powerful. - Google Search

I would appreciate if somebody could give me some ideas. Do Amazon allow their reviews to be used on this type of website through their web service?

Thanks for the help.
