General Comments
www.petrolprices.com is an excellent website to find out the local petrol prices and so help you find cheap petrol when you need to fill up your car.
I use the website quite a bit if I need to fill up for longer journeys - "look after the pennies..." and all that.
The Petrol Prices website is excellent for any price-conscious driver who is looking to save money on petrol.
