The page itself tells you to confirm bonus availability at checkout, which is good advice worth following exactly.
Choose your pack and read the order summary for the bonuses listed. Check whether they are named, whether they are digital or physical and whether delivery is described. Take a screenshot of the summary before you pay.
If the summary lists fewer guides than the page, ask before paying.
Check your confirmation email for the bonus details and watch for a delivery message. Save any download to your device. If the bonus has not arrived within a few days, contact support in writing with your order number, and do it well inside the 60-day window.
