A Slashdot post says there’s a big bookstore in Seoul

Deep within downtown Seoul, on the bottom floor of one of the city’s innumerable high-rises, is the Kyobo Bookstore, the largest of its kind in Asia. Along the West wall of this 2.3 million title shopping center is a selection of English books, and a selection of college textbooks larger than that many American campus stores. A visiting American student majoring in for example mathematics would be astounded upon browsing the selection, not because of the wide variety of books available, but because the exact same book which he or she spent over $120 on for the previous semester is available here for $30.
