They used to carry Lego Batman sets at Toys R Us, Wal-Mart, Fred Meyer and the Lego store, but the Batman sets have been discontinued, so the best place to buy them now is bricklink and eBay, but the prices will be more expensive. WAY MORE EXPENSIVE! But who knows! The new theme 'Lego Superheros' is now out. Visit the Lego website to view and buy the new products. I believe Amazon sell them at cheaper prices.
