How to get students to enrol on course packages

Hi,

I want to offer 'high-ticket' courses as part of my training packages. As an incentive to take up these I want to offer access to some of the 'lower ticket' courses, that compliment the main course, as a free bonus.

I am assuming you would do this in market press, but I am unsure how you would achieve this.

Do you have any instructional material to inform how this is set up?

Thanks,

Terry
