Just noticed this Challenge in the Shopback app, $10 back on $40 spend is pretty good considering Rebel currently have lots of ski clothing on sale at 70% off https://www.rebelsport.com.au/sports/ski-and-outdoor/ski
How to obtain in Shopback app:
• Go to 'Earn More' on the bottom bar
• Under 'Monthly Challenges', locate '$10 Rebel Challenge'
• Click on green 'Start' button
• Click on green 'Shop Now' button to start your shopping/transaction (will take you to Rebel Sport)
I'm not sure if you can start the challenge in-app and then complete your shop in a browser, I haven't tried that.
Also there's free Click & Clack or ~$8 metro delivery.
