How much is popcorn worth?

I'm curious to know, what is the actual value of popcorn? Is it determined solely by the cost of production, or are there other factors at play? For instance, does the location where it's sold, the brand name, or even the time of day influence its worth? It seems like a simple question, but I'm sure there's more to it than meets the eye. Can you shed some light on this matter and help me understand the true value of popcorn?
