Lists of price comparison services

Price comparison services or price aggregators are meta search engines for prices. See also Review aggregators and review sites‎. Many of these services are sites combining price comparison with user reviews.

It is clear that the price aggregators will continue to define the price leader and it's level in goods that are traded over the internet. We hope that people will be willing to throw in a few extra £€$ for their purchase to support a mom-'n-pop's style brick-'n-mortar more ethical SMEs over huge transnational corporations. In the digital way of doing commerce even a small operation can have a catalogue of 1,000's or even 10,000's of items to compete with the big businesses catalogue-wise and if their price is competitive then that will help drive business their way.
