Each of the 3 comes with case with lights, sounds & motion, as well little extras suited to the book's theme.

All are usually $80-$90+ (even from online sites), Big W has all 3 for $50ea (and there was plenty of stock at store I went past).
NOTE: Strangely, Bounty Hunter Code wasn't supposed to be published 'til mid/end of October, so dunno how Big W got so much stock (and on sale!!) so quick. No other online retailer (that I could find) has it to buy yet, even at full price.
On sale in Big W's "Spring Holiday Entertainment" catalogue, which runs 'til 9th October.
Cool but $50 is still a bit too expensive for basically a book on history and code of each order, inside a container.
