function ts_bogo_featured_products($cart) {
    if (is_admin() && !defined('DOING_AJAX')) {
        return;
    }    
// Check if the cart is empty
    if ($cart->is_empty()) {
        return;
    }

    // Initialize variables for the featured product
    $free_product_id = 470; // Replace with your free product ID

    // Check if the cart contains any featured product
    $featured_product_in_cart = false;

    foreach ($cart->get_cart() as $cart_item) {
        $product = $cart_item['data'];
        if ($product->is_featured()) {
            $featured_product_in_cart = true;
            break;
        }
    }

    // If any featured product is in the cart, add the free product
    if ($featured_product_in_cart) {
        // Check if the free product is not already in the cart
        $free_product_in_cart = false;

        foreach ($cart->get_cart() as $cart_item) {
            if ($cart_item['product_id'] == $free_product_id && !$cart_item['data']->is_featured()) {
                $free_product_in_cart = true;
                break;
            }
        }

        // If the free product is not in the cart, add it
        if (!$free_product_in_cart) {
            $cart->add_to_cart($free_product_id, 1);
