Just buy one NIB dude
Even if you find one for <$4K you will spend a month sending PM's, asking for pics, driving around, packing & moving a game & of course arguing with owners who paid just a tad over $4K NIB themselves in reality before adding in shipping costs.
That's a lot of drama & ass kissing just to save $700
Get a new one delivered to your front door!
Let the used games with NIB prices sit with the sellers.
Buy NIB, support Stern, give them your money
