I have noticed a definite increase in the registration fees. It used to be a cost of $8 or so for pre-registration and $10/day of show, that has now increased to 10/15 pre-registration to 15/20 day of show. Costs for everything keep going up, just look at food. The only thing that in the majority of cases don’t go up is wages. People have to make a choice where they spend disposable income.
I am more likely to spend more on a show if it is for charitable purposes.
And companies keep complaining about not being able to find workers, raise your wages.
