Other side of the pond here (western Europe), but I pay 6 in an indie cinema, 12 if I went to IMAX and similar (which I never do because most of those are dubbed).

Popcorn and drinks is usually roughly the same price as the ticket, though the smaller ones frequently forbid it - they claim for the experience, I wonder if it's that or not wanting to clean between passes.

I go weekly, though rarely American movies.
