I have to completely disagree. Amazon.com is a store, not wikipedia, and price is a hugely important factor. If folks are unhappy with the pricing on amazon.com, then amazon.com is exactly the right place for it. In particular, if folks are unhappy with the pricing of a particular item, then the review section for that item is precisely the right place to complain. They are reviewing a product that is being offered for sale. Price is crucial and relevant.
