Itinerant Salesman Question

My wife does some craft shows.
One of the requirements of many of them is that a Pa Sales Tax License is displayed
Not all require this. It's a requirement of the promoter.
I think they have too much money now and wouldn't mind if you could avoid giving "Fast Eddie" Rendell any more.
Just wouldn't want you to have a hassle.
The one thing I would consider is the possibility that there may be all kinds of gov types at gun shows. ATF, Homeland security. It also is not above Pa Revenus agents to go to things.
I don't know how often they do.
