You in the United States? If you would of preordered in June haha like I did from Walmart, you got a few exclusive bonus features, a bonus feature from the bluray, and the digital prequel comic about Supergirl, it's in video form and last almost 20 minutes. (This was a digital comic originally exclusive to Walmart for preordering man of steel movie theatre tickets) Target you get a digibook with concept art, different pictures, and an exclusive special feature that's 30 minutes long. That's all I know special feature and steelbook wise, but I imagine bestbuy will have their own steelbook. No matter if you buy bluray, bluray tin set, bluray with 3d bluray, they'll have all the special features, except those that are exclusive to walmart and target.
