It may be that $600 for “anything” is expensive to you, but that doesn’t mean that it’s an “above market” price. In fact, it may be below market, especially if it’s modular, supports facial animation, etc.
A Tesla Model S for $50,000 would be inexpensive for that car, but I still couldn’t afford it – there’s a difference in the price-of-the-work versus what-I-can-afford. Just because I can’t afford something, doesn’t mean that the market has to supply that same thing cheaper. It more likely means that I can’t have exactly what I want, and have to look around for some other way of doing things.
