This looks like an interesting site for sourcing best prices for books in Australia from international and local retailers.
A few test examples confirms what I already knew, the cheapest place to buy books is the Book Depository. We’ve been using them for over 12 months – there is no cost for freight, the prices are cheap, and they arrive quickly. It was even better when the AU dollar was stronger.
Booko is a site with a very simple goal – to find the cheapest place to buy books in Australia. This site started out as a personal itch and has slowly grown into a very handy site, slowly adding more shops for comparison and more features to make it easier to use.
