If ordered in the shop : GL.iNet Official Store (gl-inet.com)
Are the mentioned shipping costs, are those DDP or DPU ?
(“Shipping method : Express (1 week - 10 working days delivery) $28.00” is said just before checkout)
If I investigate correct, it is DPU.
DDP: Delivered Duty Paid
DPU: Delivered at Place Unloaded
Generally it is DPU, unless the buyer asked and paid the custom fee to the seller. But this is not usual for small packages.
