Since most of my readers are International Airens, the most economical site I recommend is yesasia.com. Of course you can order from synnara records or Gmarket in Korea, but the shipping will cost you almost twice the cost of the album which is 13,400 Won ~ approx $12.50 US.  Like Gmarket and other online sites in Korea, YesAsia is also including a poster with the CD.

Here is the link: YesAsia
