Ta, Rog. Looks like prices are rising again, this site might again be useful to keep an eye on the best prices locally:
www.fuelprices.grClick on Kef, select locality then click on button bottom centre (Επόμενο), click Επόμενο again then select fuel type, then Επόμενο again: in Eleios-Pronnoi prices currently seem to range between 1.575 at Valeriano to 1.645 at Agia Eirini.
