Third-Party
Guessing this is a targeted promo. Can be found in the For You page
Terms and conditions
This promotion is open to members who have successfully activated the bonus offer within their Cashrewards 'For You' page ("Eligible Entrants"). To qualify for the $5 bonus, Eligible Entrants must shop online at Amazon Australia using a Cashrewards platform between 19 August 12am AEST to 21 August 11:59pm AEST with a minimum spend of $100 (including GST, but excluding delivery and other fees) on a single eligible purchase ("Qualifying Purchase"). A Qualifying Purchase excludes the purchase of ineligible items as set out in the relevant store's special terms or items with a 0% cashback rate at the time of purchase. Eligible Entrants may track the progress of the bonus at any time on the 'For You' page in the Cashrewards website or app. Bonus will only appear under 'My Rewards', and be paid into the Eligible Entrant's Cashrewards account, after the associated Qualifying Purchase is approved by the store. Cashrewards Terms of Use apply to the use of the Cashrewards platform and any associated purchase. Bonus is limited to one per Cashrewards account and is over and above the advertised store cashback rates which still apply to the purchase. Additional purchases do not qualify for additional bonuses. Fraudulent or other activity in violation of the Cashrewards Terms of Use will result in rewards being forfeited and accounts closed.
I got this one too so maybe not targeted?
