Free Price & Call For Price app for Shopify allows you to hide "add to cart" button for free products or products for which the price has not been fixed in your web store and should be verified by phone. Moreover, for these products instead of prices in the web store will be shown the text which you can adapt in the app admin panel. By default, the text "Free" is set for free products and "Call For Price" is set for products for which the price should be verified by phone.
The administrator can easily specify that all the products, for instance, with the price of "0" should be marked as FREE or with the price of "123456789" should be marked as "Call For Price". Moreover, there is no obligation to use only such prices as "0" or "123456789", the administrator can set any price he wants.
