I understand that printing a physical book entails some cost, but what makes Bibles so darn expensive?

As an example, Lifeway has a KJV Study Bible that costs $99.99!

Seriously? The book is hundreds of years past copyright – why is it [nearly] one hundred dollars?

It CAN’T cost that much to print it – so why is it so expensive? Shouldn’t – of all books – Bibles be the least expensive? Shouldn’t we want to get them into as many hands as possible?
