Responsive eBook Shop Checkout Required Fields

Hi all,

I’m looking at using the latest eBook Shop child theme for the Responsive Shop Theme, and see that the “Delivery Details” section of the checkout page requires entry of almost all fields in that section. For an eBook shop, I only see the need to require data entry in the email address field, since the order is for digital goods, not physical goods that need to be mailed. Is there another theme, or way to modify this theme, so that email address is the only required field? Thanks for any help/suggestions.
