First deal, please be kind :) Had been keeping an eye out for a pair of Adelaide Cuban Heel boots for the missus, when I came across this. Seems to apply to a fair number of women's styles & colours.
With the 30% off, price comes down to $416.50.
I combined it with getting a discounted giftcard through Suncorp Benefits, which brought it down to $391.51.
Or if that's not an option, it can be combined with the Shopback/Cashrewards cashback deal to bring it down to $396.50.
5% Suncorp discount is a better deal above $400 purchases, otherwise go for the $20 from cashrewards.
