If you're not familiar with Humble Bundle, here's the deal: Deals.

Specifically, they're deals with proceeds that go to charity. So far, the site has offered comedy albums, downloadable video games, ebooks, and even movies, but it's teaming up with Image Comics for its first-ever digital comics deal over the next two weeks or so, and buyers can choose how much of the money they spend goes to creators and how much goes to the Comic Book Legal Defense Fund. The books in the offer are the first volumes of Saga, Fatale, East of West, Lazarus, Morning Glories, Revival, and Chew, and two volumes of The Walking Dead.

Humble Bundle uses a pay-what-you-want system, but what buyers get depends somewhat on how much they spend. All buyers get the East of West, Fatale, Lazarus and Morning Glories volumes, but to get Saga, Revival, and Chew, buyers have to spend more than the average donation. To get The Walking Dead books, volumes 1 and 20, buyers have to spend at least $15.

That would still be nine digital trade paperbacks for $15. If you bought them at cover price, they'd be $86. That's pretty much a steal.

As of Wednesday, nearly 14,500 buyers have spent just over $130,000 on the deal. The offer ends May 13, according to the countdown on the site.

This is apparently a test run for Humble Bundle to launch a comics tab in its permanent store, which means ComiXology might have something of stealth competitor on its hands, though odds are the Humble Store's library of titles will be considerably smaller. What's more, the promotion reaches out to a potentially new audience outside of comics as Humble Bundle's 4 million+ community consists largely of video game fans who may not currently be reading comics.
