Took your time, do not you have Sony? After two months of PlayStation 5 availability and several sales, the Japanese giant has done so eventually added a Deal section to the PlayStation Store. It is accessible via the navigation bar at the top once you have moved to the app and put between collections and subscriptions. From there, the page itself highlights notable promotions at the top. The new remasters and retro sale are currently housed, along with a discount for Warframe.
Scroll down and touch the offers that are exclusive to those with a PlayStation Plus subscription, and below are tab pages that allow you to access each game at a discount, separated by the platform on which they appear. It all looks very neat and tidy – just a pity it took so long to happen!
