Frequently asked questions
How do I receive my ebook?
Immediately after a successful payment you will be taken to a page with your download button. We also email the download link to the address you entered at checkout.
What file formats do you offer?
Each book page lists its format (PDF and/or EPUB). Files are DRM-free and can be read on any phone, tablet, e-reader app, or computer.
Do you sell printed books?
Yes. Many titles are available as both an ebook and a printed book (paperback or hardcover). Choose the format on the book page before adding it to your cart.
Where do you ship printed books?
We currently ship printed books within the United States only (all 50 states, DC and APO/FPO addresses). Ebooks can be purchased from anywhere.
How much is shipping and how long does it take?
Shipping is calculated per order based on the number of printed books and the method you choose. Orders are processed within 3-5 business days, then delivered by the carrier (delivery times for each method are shown at checkout). You will see the exact cost at checkout before paying. See our Shipping Policy for the full rate table.
How can I track my printed book order?
When your order ships we email you a tracking number. If you have not received it within the processing time, contact us with your order number.
My book arrived damaged. What should I do?
We are sorry! Email us within 14 days of delivery with your order number and a photo, and we will send a free replacement or a full refund.
Is my payment secure?
Yes. Payments are handled by Airwallex, a licensed global payment provider, on a secure hosted payment page. Card details are never sent to or stored on our servers.
Which payment methods do you accept?
We accept major credit and debit cards (Visa, Mastercard, American Express) and other methods shown on the checkout page.
Can I get a refund?
Yes. Ebooks have a 14-day money-back guarantee, and new, unused printed books can be returned within 30 days of delivery. Damaged or wrong items are replaced or refunded for free. See our Refund & Return Policy.
My download link expired or does not work. What should I do?
Email our support team with your order number and we will send you a new link, usually within 1 business day.
