Is there a way to remove pricing from product listings?

I want to experiment with our online business but I have a question about product listings. I have over 300 products on our auto parts store website that I originally had available for purchase online. We wanted to disable purchasing for the time being but retain the product listings. That was no problem. So I have our products listed but is there a way to batch remove pricing from the products as well without having to edit each product?

Thanks for the help as always.
