Stumbled across a couple of cheap books from Australia Post which look quite good for the young kids. Usual RRP anywhere from $15-$20… bonus with Australia Post is they offer free standard post so get both books for $9.90 delivered is excellent value. Especially as primary school kids are learning from home again.
The books are from Australian Geographic and is a mix of humour and facts, both books are 36 pages long.
Why Penguins Don't Get Cold
Why Kangaroos Have Pockets
Why Rhinos Need Friends Goes in and out of stock, so worth refreshing every now and then.
EDIT 21/07 @ 10:25am: Both books back in stock.
Nice deal OP, but real ozbargainers use their local library! ;)
