gun shows are often NOT a place to bargin hunt...unless you are buying guns from other walk-ins.
Think about it for a second. Most people who have tables to sell guns are dealers. Only gun dealers can afford to pay for space in most gunshows...or very serious specialized collectors.
So you have Steve the Gundealer. He runs Steves Shotguns N Things. Steve has in his store a Ruger LCR for $400. He thinks it is a fair price and it will allow him a decent profit.
What happens when Steve takes his LRC to the gunshow? Well, for starters he is paying $200 for the table, so if he sells 20 guns, he must sell all 20 for $10 higher than at his shop to break even on the investment of the table.
He also has to employ an additional person at his gunstore to cover the loss of the employee at the gunshow (or he needs to close his gunstore for that weekend meaning he needs to consider how many sales he will loose because of that ) Lets say he pays an employee $100 per day to be at the gunstore while he goes to the gunshow, again he now has an additional $200 in overhead for everythign he sells, which must be spread across his inventory.
Finally, he has the task of loading everything up, hauling it to the gunshow, and then returning it all to the store. Maybe he lives 3 hours away from the gunshow. Maybe he has to rent a hotel as well.
The guns he has at the gunshow have a higher overhead. Steve will almost assuredly be able to sell you the gun at equal price if not lower at his actual store.
The only reason I'd say go to a gunshow for buying guns is if...
-you are attempting to snag a deal off of other ticket buyers who bring in a single gun to sell
-the gun you are desiring to buy is relatively new and the local stores are not yet stocking it, and you like to hold a gun before you buy so no internet sales for you
-you are looking for some specific no longer in production gun(s) so you will be browsing the used racks
