Should a chocolate show that is for the public be affordable to attend?

I was looking to see when the salon du chocolate show dates are for 2012 for  New York City  and to see what it would cost and the charge was on line $35.00 and at the door $40.00.

That bothered me for I think it should be more affordable, besides paying to get in one also needs to bring money for the chocolate that is being sold there. I think maybe $25.00 would be a better price. What do others think?
