I would really love to play this game.

I liked this game For about a year now and still can't get it but i can't work because of my highschool. Stated as a law i can't work (legally). I can work on black but i don't really know how to find anyone to accept me. As for my allowence i do get it but i don't have a way to pay it over web because i found a cheaper than in store (in store it's 60 €, but online i found it for 39-42€ on vinted.) Could somebody help me to find a way to get it? I'm not looking for donations i'm just really not sure how to get the money For it and should i take online (and how) or store.
