[~K+]

You'd be able to get it for around $110HKD ($14USD) on HMV.com.hk with maybe shipping cost of around $24HKD.

As for Yesasia, I'd go with their current pricing for Memorial address OS (CD+DVD), the $20.99. And if you get it while it's new, it'd probably be cheaper, since new items are priced with a temporary discount for around 2 months. (It doesn't matter if MA is a mini-album, because OS versions are priced differently)
