I am not sure I can ask this (but I remember seing people posting some (legal) online shops so...). If it isn't, I am really sorry.

I am going to HongKong for a few days and I need to find some shops to buy things related to anime, manga, videogames. I will probably be in the touristic part of the town (I was told they aren't found there), so some places not too far away from it will be better appreciated.

Thanks you.
