Here's a holiday season deal worth mentioning. The Great Courses (formerly The Teaching Company) is offering every course on sale for $60 or less in DVD format, including free shipping (in the US and Canada). Instant video formats go for $40 across the board. The deal lasts through midnight on Black Friday.
If you’re not familiar with it, the company provides a very nice service. They travel across the U.S., recording great professors lecturing on great topics that will appeal to any lifelong learner. They then make the courses available to customers in different formats (DVD, CD, Video & Audio Downloads, etc.). The courses are very polished and complete, and they can be quite reasonably priced, especially when they’re on sale, as they are today. Click here, or on the banner above, to explore the offer.
Note: The Great Courses is a partner with Open Culture. So if you purchase a course, it benefits not just you and Great Courses. It benefits Open Culture too. So consider it win-win-win.
