There’s a deluge of games coming to Xbox over the next few months, so you’d better have some extra storage handy. Xbox Series X / S owners only have one real option for newer games: the various expansion cards you can get from Western Digital and Seagate.

Given the price hike for the premium offering — Xbox Game Pass Ultimate — just went up in September to $19.99/month, you can bag a decent saving by buying a 3-month membership during the Prime Day October deals. Why's Game Pass Ultimate so important? It's the only plan that includes day-one access to new first-party Xbox titles.

Discounts on this powerful Microsoft console can be pretty hard to come by, so there's a good chance that this deal will sell out before it officially expires at 12:59 a.m. ET (9:59 p.m. PT) tonight.
