This is a Coles Express ATM voucher deal - use the ATMS at coles express and optionally get one of the vouchers they are offering as a bonus freebie.
One of the coupons this month is for 1000 bonus flybuys points (essentially $5 when redeemed as flybuy dollars), if you buy at least $30 of Telstra prepaid credit at Coles or Coles Express. That is 16.7% off if you are buying $30 of credit!
There is a maximum of 7 redemptions per flybuys account for this voucher.
If you have an ING card, you can get the ATM fees refunded if you withdraw $200 or more. Otherwise the cheapest transaction would be a balance enquiry, if you can't get your fees waived.
Other coupons available:
15% off all freezer food at Coles (e.g. icecream, frozen meals).
$5 off Matilda Bay Cider at Liquorland
$4 off 2x brekky wraps at Hungry Jacks
Dammit I just bought a $30 recharge at the coles counter :(
