Turning off/hiding prices

Hi, I am using marketpress on my wordpress installation and would like to have my items displayed in a catalog mode, that is no cart/checkout functionality.

Marketpress supported via email claimed I would be able to do this, however I see after enabling the catalog mode option that the price of the product I defined, $0.00 still shows up in the listings.

I have searched the forums a bit, but with no definitive answer.

One hack to the default wordpress 2012 theme was

.mp_product_price {
           display:none;
}

Added to the stylesheet.css, however upon changing to another theme, it does not work.

Is there an actual way to turn off prices? I really need this as all our pricing is done over the phone.
