I cheapskate the whole cinema-going experience - I have a monthly pass that is paid off by two or three visits a month (I go twice a week - one week last month I went 5 times, but 3 of those was a LotR marathon), plus I bring my own snacks and a bottle of water. Probably works out at the equivalent of three bucks a pop plus petrol, for big, wide reclining seats and iSense where available.
