Amazon has some stellar deals on Batman Blu-rays and graphic novels for Prime Big Deal Days, and some of the items are also eligible for the retailer's B2G1 free sale on movies and books. Most notably, Christopher Nolan's Dark Knight Trilogy is available for only $34. Here's a list of other Batman Blu-rays you could add to your cart alongside The Dark Knight Trilogy.

B2G1 Free Batman Blu-rays

The Dark Knight Trilogy on 4K Blu-ray

$34 (was $71)

The Dark Knight Trilogy collection comes with 4K and standard 1080p discs. The 4K discs support HDR, which makes Christopher Nolan's gritty trilogy of Batman films look fantastic on 4K TVs that support high dynamic range (most modern 4K displays do). With this deal, you're getting Batman Begins, The Dark Knight, and The Dark Knight Rises on 4K for only $11.33 each. The $34 price is very close to the all-time low of $30, and it also has the benefit of being included in the B2G1 free promotion.

Multiple Batman TV series box sets are eligible for Amazon's B2G1 free promotion, including The New Adventures of Batman and Batman Beyond. The original 1968 Adventures of Batman is included as well, but only the DVD version. Several of DC's animated Batman movies are up for grabs, too, led by Mask of the Phantasm's 4K release and the Deluxe Edition of The Dark Knight Returns on Blu-ray.

It's not eligible for B2G1 free, but it's worth noting you can snag a 4K Blu-ray of the latest live-action adventure of the Caped Crusader, The Batman, for only $10 (was $34).
