It's pretty misleading that you only see the pricing after signing up. The landing page is all like 'sign up free' and only afterwards you have to pay $20 to do anything at all. And based on clues in the store, I would guess that once completing the course you'd have to fork out some more to get the certification but it doesn't say that anywhere. Not cool.
