This site states this directly right below its six bonus guides: confirm exact bonus delivery and current inclusion at checkout.
Since the six bonus guides are only included with 3- and 6-bottle orders, and this site hasn't independently appraised their content or value, worth confirming exactly what's included before you complete your order.
Confirm which bonus guides, if any, are currently included with your chosen package, and whether delivery is digital and immediate, rather than assuming the homepage listing automatically applies.
