KiwiWallet have some additional cash back offers for Black Friday.
I don't generally purchase because of a cash-back offer, but its definitely worth claiming if you can, and regard it as a bonus if you get it.
Includes:
Countdown
Platypus
The Athletes Foot
Skechers
Hype DC
plus others - see link.
The expiry dates seem to vary - I spotted 28, 29, and 30 Nov 2021 so I have set to expire on 28 Nov 2021.
Bear in mind with the Countdown offer, the collection or delivery needs to occur within the offer time limits. The date is not counted at the point of order.
