Hmm...
I thought we all had the ability to type a url into a browser? Is this not the case?
Here's me thinking that when i went to googles website i was using their service, i wasn't aware that their service was supposed to promote it's rivals to me! Seems an interesting concept really.
It would be like going into a shop to buy a porsche and being offered a ferrari watch to go with your car because in the interests of fairness they can't snub ferarri's own watches!
If the price comparison websites want more of a fair (read preferential, because that's what this is really about) search result for their own site then i guess they should get building their own damned search engine and get it to the place google is. Then they'll find out how tedious people like themselves are.
