Nintendo JUST launched the New Super Mario Bros 2 DLC FOR THE US. The three level packs are $2.50 each, but can be downloaded as a bundle for $7.50 for a whopping savings of .........wait for it......nothing. A bundle without a discount? Meh.
Having the notification on your system unlocks the ability to use the DLC packs in the game. They are Coin Rush packs, so Coin Rush mode must be unlocked. (Complete World 1 to unlock it.)
