Looking to buy DAI

Hi everyone! So I'm new to this sub so i apologise in advance if I'm breaking any rules/guidelines.

I recently had the urge to play mage builds in RPG games on PS4 and did some research, came across this beautiful game that is DAI.

Only problem is, I can't find it on PS store. I'm from India so maybe it's a location issue, or maybe I'm missing something because Google showed that it's available in US (priced around $30). Even chatGPT said that as of 2022, it was available on PS4. https://19216811.cam/

Can anyone please guide me on how to buy it from the store, or any other site which is reliable and at a reasonable price.

(I've checked on Amazon and it's available there but I would prefer buying it from somewhere else as I've not had great experiences buying PS CDs from Amazon)

Thanks a lot in advance!
