Cards Against Humanity, makers of the popular game for adults, is spreading some holiday cheer with a special ten days of Kwanzaa promotion.

The company has also revealed that Cards Against Humanity is now available in Australia, but the Kwanzaa promotion isn’t.

Officially called “Ten Days or Whatever of Kwanzaa”, the promotion offers ten mystery gifts in exchange for $15.

The website says, “You give us $15. We’ll send you ten mystery gifts for the ten days or whatever of Kwanzaa.”

Only the first 250,000 people who sign up will be eligible for the promotion. At press time, around 207,000 slots were still available.

In its usual irreverent style, the company answers a series of FAQs online and notes that Kwanzaa is actually only seven days.

It also says most shoppers should start receiving their gifts in early December, or at least by the end of Kwanzaa, “unless you’re Canadian”.

The promotion is different than last year’s Cards Against Humanity holiday promotion.

Shoppers can learn more about Cards Against Humanity’s Ten Days or Whatever of Kwanzaa holiday deal for 2014 by visiting a website we can’t fully print, but it’s something along the lines of holidaybullchit.com.
