Good point, I should take a look if it's easy to just opt-out. I'd be OK with these discounts in general, though they look really weird -- the course was just published, and is already "on (massive) sale" :)

Interesting.. I clearly remember the opt-out checkboxes when I was creating the course, but I don't see them anymore neither in the course, nor in profile settings. I can only change the price, but not to opt-out from the price drops. Will clarify with Udemy support.
