Shipping policy

Last updated: October 30, 2026

Thank you for shopping with Tertiary Co. This policy explains how we ship book orders, what shipping costs, and what to expect after you buy.

Print-on-demand

Our books are printed to order through our print and fulfillment partners. They are not shipped from a warehouse stock pile. Production usually begins soon after your order is placed.

Order processing and delivery times

After you order, the book is printed (typically with rush production), then handed to a carrier. Available shipping methods and estimated delivery times are shown at checkout.

Delivery times are estimates, not guarantees. They begin once the book has finished printing and ships. Times may be affected by print capacity, carrier delays, weather, customs, or other events outside our control.

As a rough guide (not a promise): many U.S. orders arrive about 1–2 weeks from the order date; international orders often take longer.

You'll receive a confirmation email with tracking when your order ships, if the shipping method supports tracking. Tracking can take time to update after you receive the email.

Shipping costs

Shipping is a flat rate by destination, shown at checkout for your address and cart. Posted prices do not include taxes, duties, or import fees unless those are shown separately at checkout. We do not currently offer a free-shipping threshold.

Shipping destinations

We ship to the countries available at checkout for your address. If a destination is not supported, it will not be offered at checkout.

International orders may be subject to customs duties, import taxes, fees, and customs delays. Any applicable charges collected at checkout will be shown before you complete your purchase. Charges collected by your local customs authority after delivery are your responsibility unless stated otherwise at checkout.

Address accuracy

Please check your shipping address carefully at checkout. Contact us as soon as possible at [email protected] if you need to correct it. Once an order has been sent to print or is in transit, we generally cannot change the address.

Lost, damaged, or delayed packages

If your order is lost, damaged in transit, or significantly delayed, email [email protected] with your order number. We will help investigate with the carrier and, where appropriate, arrange a replacement or refund under our return and refund policy.

Order changes and cancellations

Orders are sent to print soon after purchase, so changes and cancellations are rarely possible. Email [email protected] immediately with your order number if you need to try. Once printing or shipping has started, we generally cannot modify or cancel the order. See our return and refund policy for details.
