I have no doubt found that Bob at PSS will give the best trade in price of the shops around. You can certainly get more on the private sale, but dealing with Bob is quick and easy, and my experiences have always been that he makes very fair offers that still leave him some meat on the bone. He does a ton of business and on a popular item that he knows he can turn will make a good offer, and he is smart enough to know that making some on both ends of the transaction (some on the new gun he is including in the trade, and some on the used gun he is taking in) it is better than trying to make a killing on the used gun.
That said, I don't get upset if a shop doesn't make me a good offer, that part is just business. I've had several shops not even come close to what Bob has offered me on a trade.
However, the part about the Fort Liberty person running out to yell at you would have royally irked me too, and would kill any future business I would do with them, if it happened to me.
