Receive a 40c/litre off fuel voucher when you spend at least $200 on groceries in-store at Countdown. If you can only shop online, then use coupon code WEEKEND11 to receive $10 off instead (you still need to spend at least $200).
Each Voucher can be used for one fuel pump transaction to a maximum of 50 litres of fuel.
You can also get the same fuel offer at New World this weekend (or 20c off per litre when you spend $100). You can redeem your fuel vouchers at BP and Caltex.
My local Pak N Save are selling 3 pack of Up&Go for $4 a pack and they come with a $5 Rebel Sports coupon. If I buy 50 packs I get to $200 and get a 40c voucher. Rebel Sports have 40% off Nike and I can get a 3 pack of Nike socks RRP$25 for $15 which you can buy using three coupons.
So for spending $200 I can get:
Leaving a spare $10 Rebel coupon.
Admittedly you'll have to buy each pack of socks individually as you can only spend $20 of coupons per transaction.
Pak N Save is slightly better as their fuel discount isn't limited to 50 litres like Smartrewards are however with Countdown you can also each extra fuel rewards.
New World's doing the same:
Edit: Just saw this at the bottom of your deal post.
