Can I order this to be shipped to South Korea using the Apple or Amazon websites?

No. Apple online store only serves 50 United States.

But, you can use mail forwarding service provied by Bongo International http://www.BongoUS.com to accomplish international shipping. If you set up an account with it, the will be provided a US address which allows you to request Apple to ship your item to. After the item's arrival, it will be consodated and shipped to your door in your country with cheaper shipping cost compared to DHL, even 82% saving.
