I have 5 books left of the original shipment we sent to the United states. I feel bad about this, but the price is going to have to be raised to deal with the ever falling US dollar. When people pay me with their dollars, it doesn't cover the shipping costs from Thailand anymore. I will hold this price for just the next 5 books, and then I will have to raise the price a dollar or two to cover the shipping charges. I am sure most people who wanted the book have got it by now, but if not, act now.
