Some products are shipped from abroad by overseas sellers. To keep the price of items to an absolute minimum, these items are shipped by International Standard Post Office Shipping. This is why they are delivered to the Post Office as stipulated in the shipping method. For security reasons, you may be requested to provide your I.D. to collect this item. Some items are too large or valuable for the Postman to carry so they will send you an SMS or a collection slip in your mailbox.
