I suppose when people comparison-shop they compare on prices, not thinking about extended warranty yet. That part comes later.
You are also neglecting an important factor - someone who is that much into forethought and rational decision-making (such as yourself) so that he is comparing extended warranties before shopping is more likely to buy after-market insurance or better yet skip it altogether because it's pointless.
In fact, I would prefer to shop in stores with more expensive extended warranty because such stores can allow lower margins on the products themselves.
