Kmart Tyre and Auto - buy 4 tyres get a $100 Coles Express fuel card.
The promo runs between the 15th and 29th of May. If you buy 4 Bridgestone, Dunlop or Goodyear tyres in one transaction from a Kmart Tyre and Auto Service Centre they'll send you a $100 fuel card. You need to ring or register to 'redeem' the card.
They promo this as free fuel but from what I can make out its just a generic coles express gift card that could in theory be spent on whatever.
