I live in Seremban and its out here. Don't bother checking stores with big names, cos they're horribly unreliable. The normal (Miss)Understood is out here too, but without the photobook. The photobook version is arriving
tommorrow or Tuesday only at one local shop here.
Your best bet is independent stores, the normal Chinese ones. Here they sell (Miss)Understood +DVD at RM49 without photobook and RM54 with it.

Before this, I bought My Story +DVD and Memorial Address +DVD for only RM45. The price went up.
