Consumers who buy New Super Mario Bros 2 from GAME or Gamestation will receive a special coin case.
The case is a replica of Mario's iconic coins, and can hold a 'number of small objects' including 3DS game cards.
The upcoming Mario title is part of a fresh push behind 3DS, and it follows the arrival of New Art Academy and 3DS XL later this month.
The game puts a twist on the traditional Mario platforming game, encouraging gamers to collect as many coins as possible.
New Super Mario Bros 2 arrives on August 17th for 3DS.
