I'm not sure why everyone is pissed at GameStop. They can't repring without Nintendo's permission
You really can't see why? Even if Nintendo gave them permission, Nintendo can't set the price for them. If Nintendo released these games directly from their store at $90 each, people would be flipping their shit.
People are just upset because Gamestop is holding a monopoly over the "value" since most retailers wouldn't release a reprint at a nearly 50% mark-up. Despite the bitching, the reprint IS driving prices down online, so it's really win-win(for now)
