How to completely remove shipping from Zen Cart

I'm in the process of configuring Zen Cart to handle Purchase Orders only (via the Super Orders Mod) but when I go to test the cart, I can't get past the shipping screens after I have removed/disabled/uninstalled all possible shipping modules. How can I completely disable/remove the shipping so I won't have to include shipping in my final product.

The URL is:

http://sandbox.sddreamweavers.com/zencart/

This is just a proof of concept site so the samples are installed.

The error message I get during checkout is at step 1 is:

*Not Available At This Time

Sorry, we are not shipping to your region at this time.
Please contact us for alternate arrangements.
*

If I try to move to the next step the Zen Cart does not move onto the next page it just stays at this step. I would like to get rid of this step completely as my customer does not dictate shipping charges, the manufacturers do.

What can I do to resolve this issue?

Thanks in advance!

The only way to skip the shipping completely is to mark all of your products as virtual.

Thanks! One more quick question. Is there a way to make a bulk change to all the products to make them virtual or will I have to make the change one by one?
