purchase
This page covers the one product sold on the site, the full edition of the book. I kept it short; each heading says one thing you should know before paying. The text is dated 23 October 2026, and any change goes in the update log.
The full edition of the book as a PDF. The Turkish edition runs to 615 pages, the English edition to 626. The chapters in the free PDF, the research files, videos and tools on the site stay free; buying changes nothing about them. What you buy is the chapters that are not in the free PDF, the appendix, the answer key, the glossary and the full source list.
The shop page runs outside this site, on a payment provider that sells digital products. This site has no payment form, and your card details never reach me. The price, tax and total are shown on that page before you pay. Once payment is complete, the file comes to your email address through the provider's download link. The provider's name and a link to its own terms will be on the book page when the shop opens.
The file is for your own reading. You can copy it to your own devices, print it and annotate it. Sharing, selling, republishing or distributing it as course or training material falls outside that right. Short quotations with attribution are fine. Use with more than one person in a class, an organisation or a library needs a separate licence; write to me by email.
The imprint page of the file names the edition and the build date. If an error is found I correct it and announce the correction in the update log. Buyers can download the corrected file again from the same download link. A later edition that adds new chapters may be a separate product; if so, I will say so before it comes out.
Before you download the file, you can withdraw within fourteen days of the purchase through the payment provider's page or by email, and the price is refunded. Once the download starts, the right of withdrawal for digital content ends; you are asked to confirm this before paying. If the file does not open, is incomplete or differs from what this page describes, write to me, and I will send a corrected file or refund the price. Your statutory consumer rights are not narrowed by this text.
I answer questions about the file, the download and reading by email, and I try to reply on working days. Tutoring, solving a case for you or one-to-one consulting are not part of this product. I do not promise support without end; the file and its corrections are available for as long as this edition is on sale.
From the payment provider I receive your name, your email address and the order details. I use them for delivery, invoicing and support; I do not add you to the newsletter and I do not share them with anyone. Payment data is covered by the provider's own privacy policy. For an invoice, an email with your order number is enough.
The research files are published free. The site's income is book sales and voluntary support. There are no sponsors, and I take no money from any organisation or product I examine. Buying the book does not affect a finding or which case I publish.
Write to [email protected] with your order number. The shop page is reached from the book page.
