For those that never get the joy of the experience of walking into a Pawn Shop and spying that "something special", that makes your heart race just a little bit, you need to try it! Not quiet as difficult as a needle in a hay stack, but close sometimes. It is the garage sale, flea market and junk shop rolled into a guys kinda store.
I have realized some GREAT buys at Pawn shops. BUT, I have just as many times seen things at ridiculous prices. Haggling is expected, so by all means, give it your best shot. But sometimes the shop just places too much value on a particular piece for SOME reason. I think they must have regular customers that they figure will pay their price because they have deeper pockets than most, so they set the price high.
I also believe the man setting the prices has his own prejudices and some things come in he either does not have a great interest in, or does not bother to research too deeply. It is the nuance's that can make hundreds of dollars worth of difference. Pawn Owners can't know everything about everything! Ever watch Pawn Stars? The guy calls in "experts" all the time. I would suspect many pawn shops never call in any experts.
My favorite buys have been 2 very nice AR-180s that came with a load of magazines each rifle. The rifles were already reasonably priced (especially when you added up the value of the mags), but I managed to convince the shops both times that I could only pay a somewhat lower amount and they bit both times! So many people walk in and have no idea about 180s. It is fun to treasure hunt!
