If you get the lower price only with the app etc. it’s a price increase for anyone without the app. When most of the users have the app and are locked in the prices get changed based on an algorithm and everybody pays more than before.

It's just a test. Doesn't mean they won't use it the other way.

Probably just seeing how much people notice and why.

So it means gamers with fomo will never get to see a sale for the games they want to play right. Since Sony knows those gamers will pay the full sticker price.

"What is the closest number to $infinity that people will still buy?"

This is what they are testing. If you care, dont buy anything over $60. $60 is the absolute maximum price anyone should be paying for a physical copy of just a game. Digital should be even less, and Collectors Editions with extra physical items can be priced higher based on the value of the extra physical items.
