No i don't think they'll ever die out. Most people want convenience when renewing insurance or services, as well as the best deal. As long as they are under the illusion that the cheapest quote on the site is actually the cheapest they'll get full stop, people will still use them. They are, in a way, the supermarkets of the policy renewal world. I say this because it relates to what I call the "Trago Mills" theory. If you buy something from a place that is renowned for being cheap, then you're going to trust that whatever price the sticker says is the best price around. You don't then go around to 12 other shops to compare, because you've already got what you want, at what you think is the best price.
