/* No Price WooCommerce Catalogue Mode */
function wpflt_hide_price_catalogue_mode() {
      remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_price', 10 );
      remove_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10 );

If this code is used, the prices will not be visible to any users on the front end. However, prices have to be set to some exact/ random numbers in the WooCommerce backend Product List, which the admin maintains.
