This discount is part of Amazon's offical Black Friday sale, so it will likely last as long as the sale is live or until it goes out of stock. When the box set was first released it was priced at $249.99, so to see it under $100 is pretty significant. This is the lowest price we've ever seen on this set and I'd expect it to jump back up as soon as Black Friday comes to a close.
The box set includes all 10 seasons, which comes as a total of 25 discs. In addition to all 236 original episodes, there's also hours of bonus content and a new bonus feature that didn't come with the previously released Blu-ray box set.
