For Amazon Prime Day 2, you can get a Refurbished Xbox Series X gaming console for only $399.99. It's obvious Amazon made this sku specifically for Prime Day because there aren't any user reviews attributed to it. It's shipped and sold by Amazon and one of the product images shows official recertified Xbox packaging. My guess would be that this is a Microsoft Certified Refurbished console, which means you would be getting a 90-day Xbox warranty, which means it will look and work practically like new. Fortunately, Amazon does have a 30 day return policy if the product doesn't meet your expectations.
Xbox Series X Gaming Console (Refurb) for $399.99
The Xbox Series X is a current generation system able to drive 4K games at up to a glorious 120fps. It is technically a more powerful system than the PS5 and games that are compatible with both consoles usually perform better on the Xbox console. Compared to the $300 Xbox Series S, the X features more powerful hardware to enable it to run games in 4K (the Xbox Series S runs games at 1440p). The Xbox Series X also has a disc drive that can play 4K Blu-ray movies and physical game media. It is also equipped with a 1TB SSD. The capacity can be increased with either the Seagate or WD expansion cards, which happen to be on sale for $124.99 and $129.99 respectively for the 1TB sizes for Prime Day.
