A launch deadline is a date on the calendar. An evergreen deadline is a duration on a person. They enter the funnel, their window opens, and the price or the bonus follows that window. Creators know the pattern from Deadline Funnel. It exists so a course can keep selling after the launch emails stop without showing a timer that already expired.
It is only honest if the rule is real. If the price does not change when the clock ends, do not show the clock. RobinCart’s version lives in the funnel, so the cart and the deadline agree.
