jehensley on "[Plugin: WooCommerce - excelling eCommerce] How to have a "add to cart" without a price listed?"

I have a client who wants me to hide the prices on the site. However, I can't seem to get an add to cart without a price listed.

If I leave it as "0" it says "free". I would be ok with it saying nothing at all if i could find the code snippet.
