There are merch shops above ground but you haven’t explored all your options until you head down these stairs and see the treasure trove of CDs, DVDs and posters down here. —Trixie
If you haven’t read their book yet, you should go straight to the bookstore right now and buy Popped and Popped Too.
The author brought the characters to life with this tumblr and boy, how I enjoyed reading it. I hope you do too!
Just to give you a proof of the Myeondong underground shopping center, the girls in Popped was able to take a photo of it. I highly suggest you go here to find great stuff. We were able to buy stickers, stationeries, concert DVDs of Big Bang, Taeyang’s Solar Concert and Super Junior’s Super Show 2 in Japan - comes with free poster too!
