Delivery
Last updated 19 October 2026
Every book is a digital PDF. Nothing is shipped, and there is no delivery charge.
How you receive it
- Your copy is prepared as soon as your payment completes, usually within a minute.
- The page you return to after paying shows a download link and the password that opens the file.
- The same link and password are sent to the email address you gave, from books@quantpragna.com.
How long the link works
The download link works for 72 hours and for up to five downloads. Save the file somewhere you will find it again. Once downloaded, the file is yours to keep.
