MegaTagmension Blanc + Neptune VS Zombies (Neptunia) Sale somewhere ?

So google failed me , and i seen a few giveaways for the game ... since i am afraid IdeaFactory may send plutia after me if i dont own all the games in the series , i feel the need to buy it aswell ...

I tried to google it but i cant seem to find any massive discount for the game .

So if anyone know where those giveaways are coming from , much appriciated if you can share with me D:
