Coming back from the Alps in September we refuelled at the E. Leclerc hypermarket at Champfleury, just off the A4 CSR South of Reims. The peage charges for that section of the journey were €0.80 cheaper than if we’d done the same section without a stop. Might just be the case there though, as the they could be trying to encourage locals to use that stretch of autoroute. Today’s diesel price at Champfleury is €1.109, nearest on autoroute service station it’s €1.319.
