Refunds

Digital books with instant download

Because our books are digital files delivered right after payment, all sales are covered by the guarantee below rather than by a standard return.

If there is a problem with the file

If the file does not open, is damaged or is not the book you bought, write to us from the contact page, with the email you used to buy. We will fix it by sending you the correct file again or, if that is not possible, refunding your money.

15-day satisfaction guarantee

If within 15 days of your purchase you decide the book is not for you, write to us from the contact page, with the email you used to buy, and we will refund the amount. The guarantee applies once per person.
