Amazon's latest 'Buy Two, Get One Free' book sale is one of the retailer's best yet, particularly for graphic novels. It's an ideal opportunity to stock up on your favorites or cross off names on your holiday shopping list. We've curated a comprehensive list of graphic novels and comic collections featured in Amazon's B2G1 free sale. While Prime Big Deal Days concluded on Wednesday night, the B2G1 free promotion remains active until Saturday, October 12. This sale coincides with Target's B2G1 free books offer for Circle Week.

We've organized the list into smaller sections focusing on specific series, franchises, themes, or beloved authors. From compendiums of Batman and Spider-Man to graphic novel adaptations of classic novels like Dune and The Dark Tower, we've aimed for a mix of timeless classics and newer franchises. You'll also discover horror comics collections, including Robert Kirkman's The Walking Dead Compendiums, and comedic horror tales like The Simpsons: Treehouse of Horror and Stephen King's Creepshow. We've also included a selection of manga box sets, such as Demon Slayer, Tokyo Ghoul, Tokyo Ghoul: re, My Hero Academia, and Chainsaw Man, which are all part of the B2G1 free promotion.
