How Access and Payment Work

Every book can be received in one of two ways. Both are always available.

Option 1: Download free, pay later

• Choose a book.
• Download the PDF. No payment, account or email is needed.
• Read it and decide what value it gave you.
• If you wish, return later and make a voluntary contribution of any amount you choose.

Downloading for free creates no debt, no invoice and no automatic charge. A contribution is never required to keep your copy.

Option 2: Pay USD $99 upfront

• Choose a book.
• Complete a one-time payment of USD $99 on the secure checkout page. The price is shown before you enter any details.
• Receive the PDF after your payment is confirmed, together with a confirmation email.

The USD $99 covers the one book you select. It is not a membership or subscription and does not recur. If tax or payment-processing charges apply, they are shown before you pay.
