This is a post covid concept to help us sustain the business as bounce back has NOT happend yet! We go by the term and we pay costs from day one. Ide like to see demand pricing which is" it costs more due to demand" . I figure if a class is one off from being full, that place in the class is worth more than 5 places being vacant, especially if theres a wait list. Thats a popular class and should be charged accordingly. You dont need fancy algorithms just a way to set prices if a certain number of students are in the class. That also means if you enroll early you get the cheapest rate so its like a movebale early bird. It also means the regualars get the best discount and the students enrolling late, cant get it together, still on holiday, cant decide, want to pick and choose when they start and finish - well they pay more.
