Subscribe to the Humble Monthly (you can cancel before the next offer shows) and get Dragon's Dogma: Dark Arisen for US$12 (even less if you have bought the latest pwyw in the latest humble bundle.
This is the cheapest I've ever seen Dragon's Dogma: Dark Arisen go for on a non key site. Possibly key sites too. (www.cjs-cdkeys.com is showing US$12.60 for the game). Even the current sale price on steam can't match it.

 
    ![[Humble Monthly] Dragon's Dogma: Dark Arisen US $12/ AU $16.15  (PC Steam)](https://files.ozbargain.com.au/n/86/278186.jpg?h=565b2bde)



Oh, I forgot to mention when you subscribe to Humble Monthly you don't just get Dragon's Dogma but a bunch of other unannounced games too. Usually the announced game is the best and the rest are fillers but even so you're effectively paying even less than US$11 for Dragon's Dogma when you count those other games in.
