Buy Game (PS4 Iceborne) before Release Date - Where?

I would love to catch the extension of Monster Hunter World a few days before release, so I might be able to get some videos, etc. For lack of time.

Does anybody know where I'm going the best?

Or where I should try it and when?

I read that can vary from 5 days before release to 1 day before release.

I'm from the Munich area and I'm very grateful for every tip!

I'm currently in Tokyo. Here's that!
