Sony’s latest gaming console, the PS5, is one of many gaming gadgets that are hard to find in stock right now due to mostly online-only sales. If you are trying to get your hands on one, Amazon has restocked PS5 consoles right now, while supplies last (these links will help you add it directly to your cart — Disc, Digital).
I strongly suggest buying a one-year membership to PlayStation Plus, as the perks of having a subscription are great for PS5 users. Most notably, it nets you access to the PlayStation Plus Collection, which is a digital library of some of the most popular first- and third-party titles released on the PS4 such as Bloodborne and The Last of Us Remastered. I also advise picking up an extra DualSense controller.
