I really don't think you'll need to pre-order it. Pre-orders are great for if you fear that an item will go out of stock as soon as it's available. But DVDs rarely run out of stock, especially in places such as Wal-Mart and especially when its a very popular film. If The Dark Knight didn't run out of copies, I doubt Twilight will (not that it's not as good, but you get what I'm saying, right?). I guess my point is, you can probably wait until it comes out to see what editions will be available without fear that you'll miss out on it. Unless you're no where near a huge store like Wal-Mart...then my advice is pointless...
