Shipping: You will receive tracking information when your books ship (typically within two days), not at the time when you place your order. Standard orders are sent via USPS Media Mail and typically arrive at destinations within the continental United States within 5-7 business days. Priority orders are sent via USPS Priority and typically arrive within 2 business days. 

If you are located in South Korea, please contact our Korean distributor, JMK Education. Unfortunately, because of a change in Amazon policy, we are currently unable to send orders to Brazil, Australia, and the Netherlands. Books can be purchased directly from Amazon in those countries.
