Terms and conditions of use

All sales are final unless there is a technical issue with a book that we can't resolve.  You will be able to redownload any titles you purchase a reasonable number of times within three months.  If for any reason the service becomes permanently unavailable before that time you may contact us by email with your purchase information and we will send you a new copy by alternative means.

Our general policy is to do our best to ensure you have an excellent experience.
