A user who clicks a "Products" navigation link on Google.com knows he's being taken to a price-comparison page. A user who clicks an AdWord doesn't know that.
Really? So someone who searches for a camera model and sees ads like "Compare Prices on a Wide Variety of Photography Equipment & Save Money" and "Find the Right Price! Compare Shops & Purchase Online - Quick & Easy" has no idea that those ads lead to price comparison pages? I think you're being a bit unrealistic.
