Is this worth attending?

In WA in order to buy a gun at the WA Arms Collectors gun shows you had to buy a membership for like 38 dollars and then you could buy a gun... But... the stuff was usually so overpriced it wasn't worth buying at the show.
I want to go with my SIL, Grandson and Father in law but not if it's a rip off and a waste of our time...
Any suggestions/info would be helpful
