I'll be using mine in exactly two weeks time as we head for the test weekend
Hope you have a lovely time. The test day is a week later.
Péages; I've had one for 13 years now, and it costs not a penny if you aren't using it. They charge you 2€ admin fee for the month you do use it, and I use it often - most months in fact. It is not a question of the cost but the facility of use; Instead of hanging around waiting for people to put their card in and pay you just drive up in the outside lane, stop, wait for the beep and the barrier to raise and off you go. Worth every penny, or centime as may be.
