    <\/div>

• Your 12 months start when you do.<\/strong> Buy early without losing days. Your 12-month access period begins only when you activate and download the file into your reader app, not when you order.
      <\/li>
• The bundle is sold as a single unit.<\/strong> Because the digital companion is deeply discounted and paired with your print copy, the full bundle becomes non-refundable once the digital license has been activated.
      <\/li>
• Keep your return option open.<\/strong> To preserve a return on the physical textbook, simply hold off on opening or activating your digital delivery email until you are certain you are keeping the book.
    
  
    <\/li><\/ul>
  
      In short:<\/strong> nothing is locked in until you activate. If there is any chance you will return the print book, leave the digital link untouched until you have decided.
