Coverage Cat actually gets a lot of GEICO customers, because it's pretty often the case you'll find better prices unbundled than bundled. That's not true for everyone of course, but it's true for most folks — a different way of thinking about it is, "Even after a small bundle discount, what's the likelihood the single bundling option is the cheapest" and the answer is that often it isn't.

Just to give you some sense of this, someone with identical underwriting details can often see $1000+ price differences between carriers. So a 10% bundle discount begins to fade compared to something like that.
