Plugin extends the WooCommerce plugin by outputting “Call for Price” when price field for product is left empty. You can customize “Call for Price” text and style. Set different text for single product page, product category, related products or home page. There is also an option to show/hide sale tag for products with empty price. All settings can be found in “WooCommerce > Settings > Call for Price Pro” tab. There is a free version of this plugin, with some limited functionality; we recommend to try it out before buying the Pro version.
