Have you heard of Yes24? It is one of the most popular online bookstores in Korea. I have used this web site to buy some books for around 10 years. I prefer to buy books at the web site rather than buy books at a bookstore because the web site has much better advantages than other bookstores.
Yes24 provides users with many services. Among those, it is most prominent that the seller gives buyers a quite discount depending on a book.
