30% off full priced items
Should stack with Amex deals on $20 off $100 (expires today) and $20 off $100 (starts today) for the Vogue Fashion night in for an additional $40 off $100 if you have both (https://www.ozbargain.com.au/node/656515) Credit to Mr Ayayay, nightelves and wookiemonster discussing stacking in that deal.
Also deals with Westpac credit card for $20 off $100 and possibly the same with commbank credit card.
Don't think cashback would work as code not listed on sites.
