No price adds read more to WooCommerce products

Hey peterolle,
To remove the “Add to Cart” button that changes to “Read More” for products without a price and add the class single_button to the div avia_cart_buttons so the button is centered add this code to the end of your child theme functions.php file in Appearance ▸ Editor:

add_action('woocommerce_before_shop_loop_item', 'start_custom_output_buffer', 9);
function start_custom_output_buffer() {
    ob_start();
}
add_action('woocommerce_after_shop_loop_item', 'modify_and_end_custom_output_buffer', 25);
function modify_and_end_custom_output_buffer() {
    $output = ob_get_clean();
    global $product;
    if ('' === $product->get_price()) {
        $output = str_replace("avia_cart_buttons", "avia_cart_buttons single_button", $output);
    }
    echo $output; 
}
add_filter('woocommerce_loop_add_to_cart_link', 'custom_woocommerce_loop_add_to_cart_link', 10, 2);
function custom_woocommerce_loop_add_to_cart_link($button, $product) {
    if ('' === $product->get_price()) {
        return '';
    }
    return $button;
}

Please ensure to copy the code from the forum and not an email notification so the symbols are not converted.
This is the expected results:
