I'm in the US and my Essentials subscription expired yesterday and the only deals I am being offered are upgrading to Extra or Premium. Even with those deals being pretty good, I don't want to spend that much because I only play a few online games. Way to be Sony Sony.
Update: I ended up paying for a one month Essentials subscription on Friday 11/28 and then checked the Black Friday deal again today 11/30 on the PS mobile app and, because Sony be Sony, the 20% discount was magically there! I was then able to buy it.
I do not know if I needed to be a current subscriber to get the 20% discount offer, but I suspect that is the case. I used the 1 month sub for about 2 days before I checked again and found the 20% offer on the PS mobile app, so if you’re not seeing it right away, check back on the mobile app or PlayStation website the next day.
Also, it looks like the 1 year sub automatically starts after my 1 month expires, so there shouldn’t be any issues with losing out on the 1 month sub.
One last thing. This was my experience. It may not work for you. Please do not blame me if it doesn’t lol.
