Auspost are having 10% off $50 and $100 gift cards until the 13th of February. Similar to this deal on Catch of the Day gift cards
*10% off valid 7-13 Feb 2022, or until stock lasts and subject to Post Office’s availability. Offer available on pictured gift cards only. Available on physical gift cards only (excludes eGift). Limit of ten cards per customer, for personal shoppers only and not available via bulk order. Read gift card issuer T&Cs carefully before purchasing.
Just be aware that you likely won't get cashback if you use gift cards as payment for The Iconic, so 10% off is not that great when they regularly have 20-30% off + cashback sales.
