I'm just now seeing this. There was a fall Sale in September (40% off), they might have another one in the spring. DS is doing just the Minecraft Server course and he likes it. He is going through it slowly, just whenever he feels like doing a lesson on the weekend, so it's good that he only signed up for one course. If you are homeschooling or have a kid who could spend more time on it I would definitely do the "all courses" option.
