As another post notes re Germany, in the UK there is a service, internet based mainly as the ios app doesn't seem to work now, which updates prices from fuel cards and is far more up-to-date. I love the interaction with other wazers but if there is a technology solution to really enhance the service then I think this should be incorporated. It doesn't look like Petrolprices.com is a big company so I am sure they would welcome an approach.
