Toys R Us is having a buy-one-get-one-half-off sale on all LEGO books. This includes the Visual dictionaries, sticker books, Brickmaster books, and "Save the Galaxy" by Greg Hyland!
There's also free shipping on all toy purchases $49 and up. I guess these qualify because they are about toys? Anyway, great excuse to pick up Greg's book for yourself and one for a friend.
