Cards Against Humanity, the indie playing card sensation that finds participants matching up oft-unnerving responses to a question card, has been expanded once more with the release of a special holiday expansion pack, which adds 30 seasonal cards to the main set. But here's the kicker: it's available through the website strictly via a pay-what-you-want campaign, wherein you can get the pack shipped to you for any dollar amount of your choosing -- even for free.

Granted, selecting $0 will yield a follow-up screen, which berates you for being an "asshole" and reminding you that it costs them about $3 to print and ship the cards, but that's all in the spirit of a card game that describes itself as "a party game for horrible people." The holiday pack is available in the USA and Canada, and is limited to one per person.

Meanwhile, the main set ($25) and two previous, larger expansions ($10 each) are available from the website and make great gifts for friends that you're extremely, extremely comfortable with.
