This "Dollar Dungeon" was clearly made using the FREE Donjon 4e Random Dungeon Generator. Seriously. They don't even bother to remove the URL that appears at the bottom of the page! They just printed it to PDF. Don't waste your money. Just go to the Donjon website and make your own for free. It takes less time to generate the dungeon than it does to buy this product.
