Amazon's Big Deal Days event is going on now, and it includes some nice discounts on a range of entertainment products, including movie box sets. One such discount is a nice offer on the 4K Lord of the Rings bundle.

The 4K bundle, which includes all three films and their theatrical and extended editions, is available now for only $40 on Amazon. That's a pretty nice 56% discount off the standard $90 price, and the cheapest price we've ever seen on Amazon. Shipping is fast and free for Prime members, and you can order yours through the link below.

This bundle also includes digital versions of all six films as well as "Middle-Earth," a behind-the-scenes look at the creation of the films with director Peter Jackson. There are nine discs in all.
