If you don't mind me asking, is YesAsia where you got your guide books from? Looks like they have good prices for those (plus free shipping). I didn't see the guide books on Play-Asia. Also, not sure what you meant by "Pia," but YesAsia doesn't seem to have anything by that name (I'm guessing it's some kind of auto-correct typo for "Peer," but they don't have Pokémon Peer listed either).
