Dear freight, please refer to the freight template. Because Xinjiang, Inner Mongolia, Tibet, Qinghai, Ningxia, Hainan, Gansu, air parcels do not accept CDs, the owner has repeatedly returned fines for delivery, so we can only send other express delivery, so we don’t provide free shipping. Please forgive me!
