The Science of Breath is a digital PDF. Nothing is shipped and there is no physical edition. Access is instant once your payment is confirmed, and your purchase details are sent to the email address you entered at checkout.
The PDF opens on any phone, tablet, e-reader or computer that can read PDF files. If you can’t find your email, check your spam folder, then see Find Your Order.
Because this is a digital download, there is nothing to send back. If the file won’t open, you were charged by mistake, or the book isn’t what you expected, contact us from the email address you used at checkout and we will review your request and reply.
One-time payment. You are charged $14.99 USD once. There is no subscription and no recurring charge.
Payments are processed by Whop, which acts as the merchant of record. Refunds, when approved, go back to your original payment method.
