While I personally like to read a physical book, I understand that newer trends have evolved and some people prefer the digital format. The added bonus of this is that the costs of producing the book are greatly reduced. These costs are not just in printing and distribution to bookshops, but also in postage anywhere in the world that make the book prohibitive to prospective buyers.
The price of the digital book is US$9.99, plus $1 Tax. This converted to the current (at time of writing) Australian Dollar is $12.35. Even at twice the price you would be getting great value.
The payments can be made by either credit card or PayPal.
