Each and every Pawn shop. I don't make it a habit to look in pawn shops, but I strolled into one there about a year ago and found a pair of speakers, a set of B&W Nautilus 802's, NOT STOLEN, for $2,000. They had been asking $2,400 and I thought if they don't know to ask $5,000, they sure as heck won't care for a lowerball offer of $2,000 cash out the door!
