$40 DualShock 4 controllers are nothing to sneeze at but those discounted controllers won't do you any good if you don't have a system to connect them to as you'll have nothing to play. Right now Sony has its PlayStation 4 Slim on sale during Prime Day for just $250, which comes with 1TB of hard drive space for all those games.
While $250 isn't a massive savings on the console itself as this retails normally for $299, the $50 discount is still nice. What makes this a much better deal is that this is a bundle which comes with a free digital copy of the new Spider-Man game and a free physical copy of Horizon Zero Dawn Great Hits Edition. So that's $50 off the console's regular price, and two free games to boot.
Horizon Zero Dawn is down to $20 individually and Spider-man is down to $28, so that's another $48 in savings that you would have to spend if you were buying these games separate from the bundle deal. Both of these were also excellent games and some of the best on the PS4 platform, so if you don't already own a PS4 and have wanted to pick one up, and aren't too concerned with having the 4K from the PS4 Pro, the Slim is a little sleeker, takes up less space, and it's coming with two free games.
