[Prime] $20 off First App Purchase (Minimum $59 Spend on Eligible Items) @ Amazon AU via App

Found this offer while I was looking at the Sensodyne deal. If you find what you want to buy, I'd make the purchase sooner rather than later because previous similar deals seemed to be pulled much earlier than the designated expiry date. A 'Redeem' button appeared on items I looked up from Amazon AU which when clicked was saved to my account, alternatively add the coupon to your Checkout page.

Promotion terms
These terms and conditions apply to the offer where Amazon.com.au customers that are Prime members located in select areas and have not previously made a shopping purchase in the Amazon App can receive $20 off a purchase of $59 or more on “eligible items” made in the Amazon App when they use the promo code FIRST20 (“Offer”). This Offer ends at the earlier of 11.59pm (Sydney time) on 31 December 2024 or when the promo code has been fully redeemed. When we say “eligible items” in these terms and conditions we mean any product that’s sold at in the Amazon App except for (i) products sold by Amazon US, Amazon UK, Amazon Japan, or Amazon Germany Global Stores even if fulfilled by Amazon AU; (ii) clothing apparel; (iii) alcohol; (iv) digital purchases such as e-books or subscriptions such as Prime Video and Audible; (v) gift cards; or (vi) postage or delivery rates. To redeem the Offer just add $59 or more of eligible items to your Cart and then at Checkout enter the promo code and your $20 off will be applied. If the items you added to your Cart aren’t the eligible items we described above the promo code won’t apply. The promo code and the Offer are single use, so if you use the code once you won’t be able to it again. If you cancel or return an eligible item purchased using the promo code, you’ll only be refunded the price you paid for that item (ie less the value of the promo code) and the promo code will be invalidated. This Offer can’t be used in conjunction with any other offer and can’t be used on pre-existing orders. This Offer may not apply to orders placed with 1-Click. The Offer isn’t transferable and can’t be resold and isn’t redeemable for cash. The Offer and the promo code is subject to availability and may be withdrawn or amended without notice. The Amazon.com.au Conditions of Use and Sale apply and delivery charges will be applied in accordance with the Amazon.com.au standard delivery rates and policies. If you violate any terms and conditions of the Offer, your use of the promo code may be invalid, and you won’t be eligible for the Offer. Amazon may elect to cancel a transaction (and refund monies paid) if it considers that a customer is violating these terms or to address suspected misuse, abuse or fraud. Amazon reserves the right to cancel the Offer at any time where it suspects misuse, abuse or fraud.
