PlayStation 5 Slim Console - Call of Duty: Black Ops 6 Bundle

It's 50 more because it comes with a disc drive. If you get a digital only version, then you can't use physical games or media unless you buy one later The disc drive alone cost $80, so if you know you'll want or need one later, then just go with this one

One Controller

Not used. It seems too good to be true, but it's legit brand new and $50 cheaper than the stand alone Slim with Disc drive for whatever reason

Yes

It comes with a horizontal stand. A stand to make it vertical seems to be a separate purchase.
