Catalogue mode says "Free"

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.5

I have my store(s) set up in Catalogue mode because I am not using a check out cart currently. The products say "Free" unless I put in a price. I may not want to put in a price, but I don't want the products say "Free" either. Many products are on display for the customer to see the type of products carried, but they will have to call or go to the store for exact pricing and availability at the time.

So how can I get the "Free" out of there?

Thank you
