Yeah, it depends on how badly I want to see it and/or how badly I want to support it. For my wife and I the most I spend is about $30 give or take, but it has to be something I'm pretty sure is going to be worth it on the big screen. This year it's been Kong Skull Island, War for the Planet of the Apes, Valerian, etc.
This weekend we're going to catch the latest Pirates of the Caribbean movie at the cheap theater, so the total ticket price will be about $5.00 and some tax. We're probably going to stick with cheap showings for a while.
I think the most I've spend on a 4k Blu-ray so far is about $26 for Pacific Rim on eBay. But that movie's just awesome, so I could forgive it.
