www.hatjecantz.de (I own Pink, and I really want the Las Vegas book)
www.taschen.com (if you can think of it, its probably there! Great 'destination/travel' books)
www.assouline.com (great fashion books, art, design, and jewelry! most are about $20, not too horrible, I own a few)
just looking at theses websites again I've compiled a new birthday list.
