Rights concerning defective or non-conforming content and incorrect charges remain unaffected. See our Refund Policy or contact support to make a request.

Are the eBooks regularly updated?

Yes. We add new titles regularly and update existing ones. When a book you bought is significantly updated, the new files are made available in your account library at no extra charge.
