Terms of sale

Plain terms for one digital product. If something here is unclear, email henkjandekrijger@gmail.com and you will get an answer from the author, not a ticket number.

Who you are buying from

Sold and delivered by Adsfair B.V.. The price is $9 USD, paid on this site.

What you are buying

Lasting Change Workbook by John Warrior: a 78-page workbook delivered as PDF + EPUB. It is a digital download. Nothing is shipped and there is no physical copy in this purchase.

The price is $9, one time. There is no subscription, no renewal and no second charge. The price is $9 USD. Sales tax or VAT is added at checkout where required. Before you confirm, checkout shows the total including any tax that applies to your location.

Delivery

The download appears on screen as soon as the payment is confirmed, and the same link is emailed to the address you enter at checkout. It normally takes under a minute. If nothing arrives, check the spam folder first, then email us — we can resend it manually and we do not need proof of purchase beyond the email address you used.

You may read the files on any device and print the exercise pages for your own use. What you may not do is resell, republish or distribute the files, in whole or in part.

Your right of withdrawal, and how it works for a download

Under EU consumer law you normally have fourteen days to withdraw from a distance purchase. For digital content delivered immediately there is an exception: the right ends once delivery starts, provided you asked for immediate delivery and acknowledged that you lose the right by doing so. At checkout you confirm both things, and that confirmation is what makes an instant download possible.

We then go further than the law asks, because a workbook is only worth anything if you actually use it. See refunds: sixty days, one sentence, money back, and you keep the file.

What we do not promise

A workbook cannot change a habit for you. We make no claim about results, income, health or how quickly anything will change. The book collects published behavioural research and turns it into exercises; whether it works for you depends on whether you fill it in. Nothing here is medical or psychological advice. If you are dealing with something that needs a professional, see one.

If something goes wrong

Email henkjandekrijger@gmail.com or send a WhatsApp message to +31 6 55 39 56 30. We answer in Dutch or English. If we cannot sort it out between us, Dutch law applies and you can also use the European Commission’s online dispute resolution platform.
