Smokerhouser is right. If you are one of the people who "has to have a new gun today," then you will never find or seal a good deal. Sellers can see by your face that you really want one, and the price will not come down.
You have to actually have the attitude that you couldn't care less whether you buy a rifle at the show or not. After thoroughly checking a piece out, if the price is too high, then just tell them so, and walk away, happily.
I don't think I have ever been to a show where I didn't spot a good deal. I was at a very small show in Woodstock VA about two months ago. Almost all of the rifles had asking prices that were way too high. But there in a rack, among a lot of used rifles, was a J.C. Higgens branded, FN 98 Mauser, in .30-06, with all metal parts, and a beautiful walnut stock, in VG+ condition, with an asking price of just $375. One of the finest commercial mausers ever made, for just $375!
I didn't buy it, because I don't need an extra hunting rifle. But I can guarantee you that I could have gotten it for $350.
I talked to two guys at another table, who were fondling brand new Remington 700 BDLs, with walnut stocks and asking prices around $700. I told them that they ought to take a look at FN if they really wanted a deal. They were so ignorant, they didn't even look.
Another point. When looking at a used firearm, you shouldn't really care what the asking price is. They are always sky high. It should be totally irrelevant to you. You know what you are willing to pay, and that's all that should be important to you.
Yes, it may take 3 or 4 shows before you can acquire a good rifle at your price, but who cares?
