last fall on sunday a guy was walking around with a mint Benelli montefeltro I snagged for (iirc) $625...absolute steal on that gun. The year before I bought a 5.56 saiga for $460 from an individual. So i have to agree that its worth your time to ask "whatcha got there man is it for sale?"Depends. I've found great deals during the dealer setup days, or gotten parts before the unwashed masses descended upon them, but I've also found excellent deals being walked around by show visitors. Be sure and keep an eye out for the latter, you never know what might turn up. Of course, there are those vendors who prowl the parking lots, looking for deals to flip on their tables...
Also a good tip is to bring a small notepad or flash card and if you find a deal that you are on the fence about, simply write down the item description, price, row/isle and any land markers to help you find it if you havnt stumbled upon a better deal by the end of the day.
