Korea Billboard was $19.80 while K-Star was $15.35. Though for a magazine these prices may seem high, it's worth it because 1) Japanese things always cost more and 2) the import fees play a role. Besides, Korea Billboard comes with a behind-the-scenes DVD and K-Star comes with a regular sized poster (like it's huge-as big as the L's Bravo Viewtiful posters)!
I'll be posting up my thoughts on these two magazines soon! I was just too excited about finding these magazines in Seattle, especially Korea Billboard (which I saw scans online thinking I'd never get my hands on this magazine).
Update: I went to exchange my bent Billboard magazine a few days later, and it was an easy swap! The cashier (a different one) had to ask her manager first, but other than that, I was able to easily get a new, bent-free magazine.
