Humble just launched a new graphic novel bundle featuring 70 volumes in Mike Mignola's long-running comic book series. The full bundle gets you 36 items for $30, but one of those items contains 35 books on its own--so, yes, this is a lot of reading material for only $30. All of the books are delivered as PDF files. Lower-priced bundles with a smaller selection of books are available, too, but the full bundle offers the best value by far. Humble's Hellboy Universe bundle is available until October 10.

If you prefer physical books, Amazon has a great deal on the Hellboy Omnibus, a deluxe box set of four Hellboy graphic novels for just $54 (down from $100).
