NISA exclusive store sets almost always seem to sell out so I jump on them as soon as they're available. One needs only to look at the price on Neptunia Mk2 where it was sold for $60 from the store, and sold out directly from them only to wind up being sold at triple the price online after release.

Most modern special editions are overproduced though, walls of Halo 3 helmets and Skyrim statues abound in the videogame graveyards.
