Just came across this deal. Apply for a new Shell Fuel card (ABN required) and receive 8c a litre off at Coles Express branded sites, 8c off at unstaffed sites and 4c off elsewhere.
Deal is only valid for three months and applications can be made until the 31st of May, 2015. Does have a card fee of $4.40 per month (55 litres needed to purchase each month to offset). ABN required.
What about after 3 months?
