If you are a PC gamer, then you may already know about Humble Bundle, each month they offer 1 or 2 games for $12 at the start of the month, at the end of the month you unlock a ton more games for free.
For the month of February 2018, Dark Souls III plus the DLC is $12, click the link and check it out Humble Bundle.
Each month they also offer other bundles as well, hell just a few months ago I got 4 PS4 games, all listed for more then $20 on PSN, a bunch of PS3 games and some other stuff for all less than $10.
