Where can I find the VCDs for the "十万个为什么 ?" education series? I saw it in Challenger a few months back selling for only $19+ per set but recently they stopped selling it. I asked them when they will be selling it again, and they said they won't be bringing in anymore. :cry: Popular sells it at $50+ for the same thing. Overpriced! Anyone knows where can I find it cheap?
