Movie theaters should sell "limited edition" merchandise (tshirts, posters, figurines, comics, games...) in a gift shop for profit rather than charging $5 water or $15 popcorn

I spent $5 on water. I could've paid 3 and got Starbucks. How does that make any goddamn sense?

Here's my idea: Star Wars opening night. First showing lets out. Gift shop is on the exit. Limited edition screen print. Maybe even theater specific prints. Charge, $5 to Moon money, whatever people are willing to pay for collectibles. Profit goes up and maybe the price could come down on $14 popcorn back to more acceptable number. And a $5 water to 99¢ or what a machine would cost.

I think this would help attendance for opening nights for big block busters and maybe help recover profit loss from pirating since all these collectibles would have to licensed and royalties as well. This isn't really a perfected idea but would love to discuss and use this idea to help :)

Sorry for any grammar issues.
