So you never use Amazon for product discovery or evaluation? You've never gone to a store and said "I wonder what Amazon prices that at and what people say about it?"
Sure I did. But by that time I know exactly what I want to buy - I've discovered the product and evaluated it compared to alternatives prior to setting foot in the brick&mortar store (I don't trust store salespeople either). I never do casually browse Amazon, or type a generic description and buy something from presented search results.
As for "what people say about" a particular product on Amazon, I don't even bother reading it.
