This is a referal link incase you wanna try it yourself.
I was trying to buy Dark Souls 3 and on steam it sells for 59.99
With a little research I found this website and gave it a shot, I paid $12 for the first months membership and was able to download Dark Souls 3 and one of the DLC. I also got the game Overgrowth.
The great thing is even if you quit your membership you get to keep the games you've already claimed.
You're also encouraged to discontinue if you don't find any of the games for the next month to be of interest.
Last month they gave out Civilization 6! Another game I wanted but sadly missed that pack! :(
If you do try this membership let me know what you think!
