Gift item can be added as per this solution - Buy one get one in woocommerce with out coupon code .

You can add the following to your theme's 'functions.php' to remove the gift item added automatically by another product.

function remove_gift_product($cart_item_key) {
    global $woocommerce;
    $cat_in_cart = false;
    $coupon_in_cart = false;

    $autocoupon = array( 123411 ); // variation ids of products that offers gifts
    $freecoupon =  array( 2046 ); // variation ids of products that are gift coupons

    foreach ( $woocommerce->cart->cart_contents as $key => $values ) {      
        if( in_array( $values['variation_id'], $autocoupon ) ) {  
            $cat_in_cart = true;                
        }       
    }

    if ( !$cat_in_cart ) {          
        foreach ($woocommerce->cart->get_cart() as $cart_item_key => $cart_item) {
            if ( in_array( $cart_item['variation_id'], $freecoupon )) {             
                $woocommerce->cart->remove_cart_item($cart_item_key);
            }
        } 
    }
}
add_action( 'woocommerce_cart_item_removed', 'remove_gift_product' );

Add this if you want reduced price for your gift item.

function add_discount_price( $cart_object ) {
    global $woocommerce;
    $cat_in_cart = false;

    $autocoupon = array( 123411 ); // variation ids of products that offers gifts
    $freecoupon =  array( 2046 ); // variation ids of products that are gift coupons

    foreach ( $woocommerce->cart->cart_contents as $key => $values ) {      
        if( in_array( $values['variation_id'], $autocoupon ) ) {  
            $cat_in_cart = true;                
        }       
    }
    if ( $cat_in_cart ) {
        $custom_price = 0; // This will be your custome price     
        foreach ($woocommerce->cart->get_cart() as $cart_item_key => $cart_item) {
            if ( in_array( $cart_item['variation_id'], $freecoupon )) {
                 $cart_item['data']->set_price($custom_price);
            }        
        }
    }
}

add_action( 'woocommerce_before_calculate_totals', 'add_discount_price' );
