Min. Spend: None.
Dates: Wednesday 24th Nov 2021 6:00pm to 8:00pm AEDT.
You can place multiple orders, but there will be a Cap of $25 Cashback Per Customer.
If you wish to place multiple orders, you must exit and re-enter through our ShopBack links between each transaction for all orders to track.
For orders over a combined value of $275, you will initially receive more than $25 Cashback, which will later be updated to exactly $25.
Items sitting in your Amazon cart prior to clicking through our links will not be eligible for the Flash Sale Rates.
I advise you to add the products you want to your Amazon Wish List for easy access.
You must click through our "Amazon Flash Sale" page for your order to be eligible for 10% Cashback.
Clicking through the standard Amazon Australia merchant page will result in Standard Cashback Rates.
