Our textbook is provided in a PDF format and cannot be retracted once the customer has received their copy. For this reason, we like to manually verify orders to ensure that they have been processed correctly before providing the download link. Once your order has been verified and completed, you will receive an email notification informing you that your copies are available for download.
The PDF has been encrypted so that you cannot share this without being personally identified. Any attempt to share this resource without the proper licensing will result in legal action to the full extent of the law.
