This was previously answered by Vasco Cavalheiro who said you can have 4 separate courses and charge for each separately on the same website — you’ll need one coupon per course. If you want a standalone course on a separate domain you can do that too (e.g., 5 courses: activate 4 coupons on site A and 1 on site B); all students for the 4 courses on website A will be on a separate list from website B. He recommended getting one code, activating your first website, trying it out, and letting him know.
