If you’re in Australia (or that neck of the woods) and you’re interested in buying one of my books in paperback, here’s a tip which might save you money.
My books published print-on-demand with KDP Print are prohibitively expensive in Australia because Amazon ships them in from the US, and you have to pay for the postage.
But Book Depository in the UK offers free postage!

The downside is the books are more expensive to start with.
But do your comparisons. You might save some dollars.
