There's a handy little site which may be of use to some of you. It's a (free) list of petrol stations that are downloaded to various GPS units as POI's with the price of the petrol/diesel next to them (with a marker showing if the fuel is more/less expensive than the national average). The prices are updated daily, apparently. The site's in French, but is easy enough to navigate. A free account is needed, but I've not been spammed (as yet).
