CUPONATIONDEL
After doing a bit of googling to try and find free shipping for the Adidas deal (https://www.ozbargain.com.au/node/384687), I stumbled upon this code and it worked for my other order (couldn't get through checkout like most others with the EQT in the cart).
Thanks to https://www.cuponation.com.au/jd-sports-coupon for the code.
Enjoy!
