Its not worth unless you take Mentor Program after 2.5 day course. And mentor program is bit expensive for beginner.
I have attended 3 days master class, Julian covers most of the time about the mindset and how to prepare for ecom business, master class was nice and useful. but initially I thought 2.5 days is enough to learn, but he try to upsell additional mentorship course to take to be a successful ecom owner. I would say 2.5 days is another marketing class like which you attended earlier to sign up this course. This course will be useful only if you are ready to take mentorship program, otherwise don't waste money for 2.5 days class.
