Some countries charge extra taxes on importing goods. The UK states that packages valued less than £15 (About $23 USD) are exempt from VATs (source: http://dft.ba/ukVAT). When we mark the value on customs forms, we do not include shipping costs, only the cost of the actual item.
Please note that you may be charged taxes upon import of your items. We are also unable to ship your merchandise as a gift (even if you are intending to give the item as a gift to someone else), as we need to follow the rules and fill out each customs form correctly. If we don't fill out the forms properly, we risk having the shipment returned to us or being prohibited from shipping to that country.
