Steelbook Prices

I’m new to the steelbook game (few months), but Steelbook prices are crazy. I was looking at an old post about the pre-order for Cabin in the Woods and was shocked to learn that steelbooks were $19.99 previously and for Cabin in the Woods it was $24.99. All I’ve known are $34.99 steelbooks. Do you think Steelbook prices will ever go back down or continue to go up?
