Important note for EU citizens!
The quoted prices for my books ($29.70 for one or $51.40 for the discounted package) include 10% GST.
GST is the Goods and Services Tax charged in Australia.
It only applies to Australian customers.
EU countries charge around 20% VAT!
(Value Added Tax, Umsatzsteuer).
That makes my guides more expensive for readers from the EU. How expensive depends on the country you are from.
The tax will be added automatically when you check out.
Unfortunately there is nothing I can do about that.
(Luckily this is an e-book, so at least you save any ridiculous shipping costs!)
