Pawn Shop cruising is like buying a used car. KNOW what you are looking at and don't be afraid to walk away. Having said that, I have bought a LOT of stuff over the years at PS's. Rarely have I ever felt I got jammed, unlike many new purchases at "actual firearm dealers".
ANYTHING new will lose value when you walk out the door, PERIOD!!!!! Know and understand that. PS guns (or most anything else) on the other hand, have already taken a HUGE depreciation and it should be reflected in either the tagged price, or what they are willing to take. Business is business, so of course they will mark a gun at $400 but may take $200 for it. Why not? If YOU were running a business would you let $200 fly out the window for NOTHING? Maybe a guy will walk in who just HAS TO HAVE IT and pay full price, or maybe not. Remember....don't be afraid to walk away if the sales guy/gal won't deal. Always ask for the Manager if they won't negotiate. Pawning is a business that has an enormous cash flow!!!!!! But, they have to keep merchandise moving for that cash too flow.
I was with a friend ealier this year and we were cruising the "Discount" rack at a local PS. Yes, even PS's will occassionally have merchandise they want to "fire-sale" and get rid of. He found a near perfect Chinese SKS for $99. Complete with box, cleaning kit, bayonet, ect. This was the same week we saw a beater SKS sell for $350 at a gun show.
There are some SMOKING deals at PS's sometimes, but you have to know what you're looking at and what it is worth or you can also get SCREWED!!!!! Hmmm, sounds just like every other kind of business or item purchase now doesn't it?
