Is shipping included with the 50% discount?

While we attempt to offer a variety of shipping options, we do not have control over shipping costs and fees. We realize the cost of shipping to some parts of the world is at times prohibitive. While we can’t control this, we recommend exploring our ebooks and audiobooks, which are also included in the 50% off sale and available worldwide.
Can I ship my order outside of North America?
Yes, the 50% off sale is available worldwide.
I am shipping a book to the UK or Europe. Must I supply a billing address in the UK or EU?
Yes, for books shipped to the UK or Europe, a UK or European billing address is required.
My order is shipping outside of the United States. Will I be charged any additional fees?
Print book prices quoted exclude taxes and tariffs. If the destination country applies tariffs or taxes on print books, you may be required to pay the VAT or GST amount to the carrier who will advance that import VAT payment to the relevant authorities on your behalf. Any other applicable tariff, duty, taxes or customs clearance charges required by the destination country for importing consumer goods are your responsibility and will be charged to you by your carrier.
