From a technical perspective: prices change constantly; prices are inconsistently expressed and the volume of products is massive. Scrapping the volume of data required and then processing it and updating it is a substantially difficult task.

From a business point of view an independent operation would require a very large investment. To recoup at least part of that requires advertising and affiliate revenue which in turn creates perverse incentives.

That is a good point because there are so many products all over web and would need a huge search to find even a small amount of Google. Thanks for your feedback!
