Maybe it's a dupe but while deals were posted for seasons 1 and 2 of The Walking Dead at the moment, they didn't mention that the DLC 400 Days was also 75% off and I've never seen it included in any of the humble bundles or previous steam sales
The Walking Dead, 400 Days DLC on Steam, $1.64 AUD, 75% OFF

90
It is quite often this price, didn't make it not a deal though.
