Did you see any? The last post in this thread was almost 6 months ago.
I wouldn't hold my breath for a coupon either, the course has over 2500 students, and it is considered a best seller. Unless the course somehow drops below a 4 star rating, it's highly unlikely that you'll see this course for free again.
