Do Not Capture Shipping Address if nothing is shipping

We are a print and mail house. Most of our products do not ship to our customer. When a customer is ordering from use they upload a mailing list of their prospects and we mail directly to their prospect. However when a customer is checking out our customer's address shows up as the ship to address. This confuses the customers and creates abandoned carts, and more customer service calls. We have plenty of verbiage on the site, but customers don't read it. They just see ship to. I would like the option when shipping is $0 to turn off "ship to" in the shopping cart, and display a default text.
