Yes, we have many courses from them, and most are great. For history, the best we've had so far was Bob Brier's
History of Ancient Egypt. Overall that prize probably goes to the
Particle physics for non-physicists: A Tour of the Microcosmos, which your DS might love as much as mine did! Joy of Maths and Maths of the Visual World are also fun, and various others that I'm not remembering now...
The only disrecommendations I have so far are for the high-school chemistry course (which starts with a presumption that you hate chemistry but need something to get you through the exam) and the Nature of Earth intro to geology one, which has way too many mistakes in basic physics to be recommendable, even though it is enjoyable.
PS Make sure you understand their rolling sale policy - basically, never buy anything that isn't on sale, a sale will be along shortly!
