I live in FL. Gun shows here are a booming biz. There is a show circuit. Google FL gun shows. 1-2 big shows weekly within driving distance. There are no good deals at the big shows. Its entertainment. Its the movies. If you can find a small local Elks or club show its still somewhat old school.
Everything is overpriced. There are no good deals. 1/2 the tables here are pawn shops. Largest gun dealer in Florida (Shoot Straight) runs a traveling show (Florida Gun Shows) like Barnum and Bailey. Probably has 100 employees or more at each show just for his gun tables. The Tampa show probably has 20,000 ppl a day or more. Its all pistols and ARs. Hundreds of tables. No bolt guns. No hi grade rifles or shotguns. Funniest thing is there will be 5-10 ppl selling hi end glass. NF/SB/US/Votex ext. i needed a NF mount for a project a while back that popped up at the show. While there was probably 2 million dollars or more in hi q glass for sale and none of it you would put on a gas gun, not one vendor had a NF mount or even $20 one or two pc mounts for a rem 700 short action. Not a single action, Remington or anything for sale. People have old guns in 70% condition at exhibition prices.
There is not a thing there new or used a person cannot find cheaper on line or at small gun shops and have in hand in 2-5 days.
I watch local gun trader sights to find bargains.
If I didn't have to be at gun shows, I wouldn't ever go.
What you are seeing is Google/internet killing the "Gun Show". There are few deals to be found because you can not only research every gun, scope, nut, bolt and part, you can also find a dozen places to sell them to people who want whatever you have. Deals used to come from knowing something the seller didn't or the buyer being the bird in hand. Those days are gone.
