You can buy it from the creators, FeuerLand, here: http://www.feuerland-spiele.de/shop/They accept PayPal. I bought it from them and it took about 2.5 weeks to come to the USA.
If you want to wait, you might be able to buy the Z-Man North American release in a few months. I don't know which will be cheaper if you are ordering from Brazil though.
