For delivery to certain countries, applicable tax & duty may be charged at checkout and you should not be subject to any additional charges. 

For all other countries, sales tax or duties may be collected by Passport (our international shipping partner) on behalf of your local customs office before or upon delivery; as per the terms and conditions when placing your order. 

Some local customs offices may apply sales tax and duties against the full retail value of the complementary or discounted item(s). They will review the value of the product at retail price and not view this as a free or discounted item.
