It's a bit like software pricing, the marginal cost of production is low. You often see massively different prices charged to different types of customer.
I used to support an application used by about half a dozen businesses. They all knew each other, that's how I got their business.
Two of them were paying significantly more for their support than the others. That's because those two had their phone numbers set to ring even when my phone is in quiet mode. Just for the privilege of being able to wake me whenever you want, and get my attention even when I'm in the middle of a hike, you're paying substantially more.
