Not all shipments will include tracking without request. In some countries, tracking is automatic on orders, but this is not true in all countries. If you want to make sure tracking is included, please tell the seller that when you place the order. You may even be able to select it as a shipping method when checking out from your shopping cart.
It is the buyer’s responsibility to always make sure to review the seller’s Shipping and Payment terms (available on the seller’s profile page) before placing an order.
