People go too crazy over these "limited" collectables.
For all we know, Nintendo might start giving these things away again as part of a My Nintendo promotion.
"Twilight Princess is coming out and will blow you away. So we're giving away it's E3 trailer, playable on a DS cart, to loyal Zelda fans who've got The Wind Waker, Four Swords Adventures, and The Minish Cap, all registered with us."
I'd pay five bucks for one. And I'd hold out for a seller that's not trying to rip me off on the shipping costs.
