These aren't exactly Deals or Freebies, but these are several sites I use to find and track deals. I have alerts set up on some of them so I get notifications when games on my wishlist go on sale.
https://gg.deals/ (my favorite deal site)
This board is where you can share all the good deals you've found across the internet. Lots of free and cheap games out there. Always good deals on hardware. If you found something you want to share, please post it in its own thread on this board.
