Sadly, LEGO Batman is not manufactured any more, however a great place to buy Lego Batman is Ebay.
They have new LEGO Superhero Batman sets, though old LEGO Batman sets they don't really sell in stores anymore but I'm sure you can pick it up off eBay or Amazon.
only on lego stores
They sell it online at walmart.
they do
Gamestop and Amazon are online stores that sell LEGO Batman games for a number of consoles. These include Xbox and PlayStation consoles. Gamestop also has stores in various places so have a look at the website to see if there is a store near you.
There are many online websites that sell Lego Batman toys. Amazon and eBay both are two sites where Batman Lego toys are sold and can be purchased from.
yeah and toys r us should sell them
if you are talking about 2006 batman then no however there are superheroes batman(2012 version)
your nan sells legless Lego robins, but batmans are for the special people and you need to get an invite to a special Lego batman giving seminar:)
On ebay I know they have a wide selection of Lego Batman for buy it now (no bids).(see the related link)
Now they should sell Lego Ninjago in all Lego stores including their website.
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.
