Since nearly every OzBargainer now owns a Kindle after the latest clearance deals, I spotted a (rare) decent book in the Daily Deals, which is usually peppered with unknown authors and bad romance novels.
Only available today, it's The Martian by Andy Weir.
The paperback will set you back $17.70, so $4.99 for this quality read seems like a deal.
It's yours to keep for as long as Jeff Bezos rules the universe (or moves to Mars).
Great book.
