Exclusively for Prime members, Western Digital’s WD_Black C50 1TB Storage Expansion Card for Xbox is on sale at Amazon for $120.64 (about $37 off), very nearly its lowest price to date. You can also get WD’s 512GB card for $65.54 (about $14 off), a few dollars shy of its lowest mark.

Amazon Prime Day Xbox Series X deals have returned for the second time this year, meaning there's big savings to be had on a wide range of Xbox kit. And while we're not currently seeing discounts of any shape or size on the consoles themselves, there are discounts on controllers, headsets, accessories and the like.

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.
