If you directly buy Kandagawa Jet Girls on PS store at
https://store.playstation.com/en-us/prod...WAJET0000/

It costs $49.99 as of August 2021.

But you can buy the game at Publisher's official website at https://store.xseedgames.com/product/kan...jet-girls/
They sell it for $29.99 instead. It's almost 40% cheaper.

I think this price is almost similar when Kandagawa Jet Girls goes on sale on PlayStation Store.
