What is going on with these concession price increases??

Last year, I bought the Wowful ice cream for $13.75 with tax. Today, for the same ice cream I paid $16.33. That's an 18% increase. I get inflation is higher than normal, but 1) the prices are high already and 2) inflation is not 18%. Is this as a result of the pitch clock causing less concessions to be sold? Regardless, Idk if I want to buy from concessions if this is the crazy price increase they are having.
