Your link leads to an Audible Audiobooks webpage offering the The History of Ancient Egypt course for $52.95, clearly stating it's from "The Great Courses."
But when I go to The Great Courses website, they're charging $249.95 for (what appears to be) the same course!
Quite a difference.

As an audible subscriber you basically pay $10/book, no matter what the “listed” price.
