Sometimes you can get a deal on accessories at a gun show and sometimes not. I saw a cheap cleaning kit at one in E'ville some years ago then saw it later that day in, of all places, Gander Mountain. It was about 10% cheaper at Gander. The seller probably bought an armful at GM then sold them to people who didn't know a good price at the show.
"and most times NOT".
If you've not been to a gun show, I think you may be a little disappointed. People expect to find all these great deals and typically, they're just not there. I'd support your local gun shop or other local business and get your stuff there.
Some people like them gun shows. I'm through with them. Just wasted parking and admission money. Just my opinion.
