Hi, I'm informing you about the payment plan. If you say which textbook you want, we will send you an estimate by e-mail, and we will check and deliver the textbook once you deposit the textbook into a copy of our association's bankbook. (Please note that other methods are not allowed.) The international delivery fee is about 100,000 won, and after we ship it, we can charge you the international delivery fee and you can deposit the international delivery fee in the same way as the textbook payment. If you still want to buy it, please contact me (shale7@ktbook.com) Sincerly, Korea authorized and approved textbook association
