It is currently $3.74 USD on Amazon. I would purchase the game myself, except that Amazon has a region policy for digital games and won't sell it to me as I don't live in the US.

According to this thread in /r/GameDeals, the key adds both Don't Starve and Don't Starve Together to your steam library, despite the page on Amazon only mentioning Don't Starve.

The main reason that I want to play Don't Starve Together is to experience the Touhou mods. From what I have seen of gameplay videos on the game, it is a survival game with roguelike aspects (such as permadeath). It is considered to be one of the better survival games available, and is one of the top 100 best sellers of 2016 on Steam. While I have never played a game with a focus on survival before, I am keen to give it a try.

EDIT: Nevermind; was able to get pass region restriction by changing my country to US in the "Manage Your Content and Devices" settings.
