ELI5: How does Humble Bundle make money when they have discounts that cost them hundreds of dollars each sale, and only make a percentage of the discounted sale?

It helps a lot that they aren't selling a physical product. Really cuts down on the cost per unit.  No materials, no production cost. Just licensing and server costs (bandwidth). 

So to say that it's 'costing hundreds' isn't accurate, they're almost certainly not dropping the price below cost, even though to us consumers, it seems like a crazy discount.
