Sales Tax and Duty
Shop prices exclude taxes and duty. For some countries, there is no duty or sales tax on physical books and in others, sales tax may be due on both digital and physical books but at different rates. Sales tax will be dependent on your "ship to" location and may be visible in your cart. If no sales tax is calculated, you may still be required to pay sales tax to your tax authority prior to receiving your order.
