Erik opens the courses up regularly (I would guess every 6-8 weeks). If you sign up for his newsletter (which is also quite good, almost completely original substance like his blog) he will let you know when registration is opening. The approach is definitely unconventional - I would guess the main reason is that selling a high ticket item like this benefits from a longer sales cycle. The other reason he might do this is he has a Slack group where students can post their homework assignments and get feedback. So having a cohort start at the same time might be desirable. As a consumer I would agree with the comments that I would prefer to have them always available for purchase. If you do buy one of them, he makes all of the other courses available at any time. As I mentioned in my post, the price is probably around $1000 for the UI course; the other courses are typically a few hundred dollars cheaper (they aren't quite as long). The course prices do tend to increase over time, and I think Erik is very averse to offering discounts.
