I presume you're in Germany? Where do they make you pay 15-20€ per ticket? I just bought a cinema ticket today. The sticker price was 10€, and I got it for 6.60€ with a loyalty card (Cineplex High Five, completely tracking-free since I bought it with cash).
Mind you, this was almost 10 years ago but I could swear it was something like 16 or 17€ per ticket.
I just looked it up though and apparently it's 7-8€/adult now depending on the day.
I can order practically any movie DVD/BR I want from reBuy or momox via Amazon including shipping for less than just the ticket price, not to mention time investment etc.
