I ordered this book about 2 weeks ago and received it today. Not too bad considering it came all the way from Japan.
I ordered it from a seller on Ebay whose seller id is 'bookstoron'. I've ordered from this seller before and have had no problems whatsoever. I highly recommend her (or him - I'm not too sure - the name is Hitoshi). I also received a nice surprise in my order - an origami crane made with pretty paper. I will collect them to make a mobile.
