Let's say you just bought a shiny new PlayStation 4 and you want to play a game with a friend at your house. Unless you also bought a second controller, you're going to have to take turns handing your gamepad back and forth. That's because most PS4s only come with a single controller. To protect your dignity and reputation from this kind of social blunder, you'll probably want to buy at least one more controller. And if you do it now at Newegg, you can save a few bucks.

Right now, you can get a brand new DualShock 4 wireless PS4 controller for $45-$49, depending on the color you choose. That's a good deal, considering these controllers normally sell for $60-$65 each.
