THE French government has created a website that allows you to compare petrol prices between supermarkets.
The prix-carburants site collects data from around 8,000 shops across France, narrowing down your search via communes - unfortunately the popularity of the site means it is struggling to work at the moment.
However, late last night I was able to check it out and the site offers a quick and simple way of seeing the price of standard unleaded and diesel.
The results page displays the name of the supermarkets closest to your chosen town and lists the individual prices per litre.
Although there are a large number of supermarket petrol stations included in the site, around 5,000 have not provided up to date figures and face a fine if they fail to do so.
Hopefully the site will be running smoothly soon and make it easy to compare petrol prices across France.
