Huh?
Since...I don't know......FOREVER?
Any NIB pin from Stern that I've got a quote on ALWAYS includes the "shipped" price. When I go to sell, I always consider what I or anyone else would have had to pay for the pin new. Then discount accordingly for the current market and no longer being NIB etc.
But more to the point: If I bought a NIB pin from Stern and paid $6.5K shipped, and something came up requiring me to sell before opening it, you can damn well bet that I'm going to ask close to $6.5k for the game. If someone local wants the pin, they'd have to pay close to the same price for a NIB since they'd have to pay shipping too. So why wouldn't you ask for the total shipped price paid, or close to it?
Shipping is part of the cost of a NIB pin.
