Update: for the latest revision of this list go to Popular price comparison sites – March 2011.
This is a list of all price comparison web sites that I am aware of. I included the sites with Alexa ranking less than 100,000 or Page Rank 5 and higher. The list is sorted by Alexa rank (more popular sites are closer to the top).
I will update this list every month. Feel free to let me know if there is a price comparison site that meets the criteria above and needs to be included.
