The 30-day promise

If a book is not what you expected, email hello@zentesto.online within 30 days of purchase and we refund the full price. You do not have to justify it, and you can keep the file.

How to claim

One email with the address you bought with and the order date is enough. We reply within two working days. The refund goes back to the original payment method, usually within five working days of our reply.

When we may decline

A refund on the whole catalogue, repeated claims from the same buyer, or a claim made after the file has been redistributed suggest the policy is being used to get the library for free. In those cases we will say so plainly and explain our reasoning.

Books bought elsewhere

Titles bought through another retailer are refunded by that retailer under its own policy. We cannot issue a refund for an order we did not process.
