I can't really help you with your situation too much, sorry, But I will try my best:(, Firstly I order most of my games from Amazon and nothing has gone wrong for me and all the delivery's have come on time, I even have Skyrim preordered for release date delivery and I have full faith that Amazon will deliver it to me on time and not mess me about, So yes from my experiences it is very safe. But I live in the UK and I've read on the UK website that they don't deliver to Brazil so you can't order off there, you'll have to order of the US Amazon which will be exactly the same as the UK website. I'v looked up that It will cost $59.99 for the game plus $4.99 for standard shipping to Brazil and that It will take 16-30 days to arrive or you can pay more for it to Be delivered earlier. The Link gives you information about Latin American delivery times and postage prices, http://www.amazon.com/gp/help/customer/display.html/ref=help_search_1-1?ie=UTF8&nodeId=596202&qid=1316821605&sr=1-1 I hope this helps:).
