The Program
The program encourages Amazon customers to try products from select categories for the first time and be rewarded with a $10 voucher for their next eligible order over $39 (the “Offer”).
Enroll in an Offer: Customers who are invited by Amazon or clicked through on-site marketing whilst signed into their Amazon customer account, are able to enroll in an Offer through the program landing page. Actions taken before Offer enrollment are not entitled to any associated reward.
Complete eligible purchase within the Offer’s period of validity: Once enrolled, an Offer needs to be completed within its period of validity (10-days).
Receive & redeem reward Voucher: Your Voucher will be automatically applied to your Amazon account after completing the Offer and your item has been dispatched to you. On your next order, once you have added at least $39 of eligible items to your cart, your $10 total discount will be automatically applied at checkout. The Offer reward Voucher applies only to items ordered on Amazon.com.au, that are sold by Amazon AU or Amazon Commercial Services Pty Ltd ("Qualifying Items").
