The recently released Super Mario Bros Monopoly has proved to be a success and subsequently Amazon were quick to mark the product as out of stock. If you didn’t get to pick it up the first time around you can back order it for June 12th. It will cost you $39.98 so it’s slightly cheaper than what you would pay if you purchased it from a seller.
Amazon: Super Mario Bros Monopoly Available Again June 12th

I didn’t think this Monopoly was even released yet. It wasn’t at Hastings (the only local store that ever gets special edition Monopoly games) and they didn’t have it. Must only be online at the moment.
can you actually get this as a board game?
Yup, as are former Nintendo themed board games.
