I stumbled acros something very useful. It’s an application which helps you with saving money on French tollways. I have alreay used it and it helped me save some money. I highly recommend it to everyone who is sick and tired of having to pay so much toll in France.
It’s called ”péago”. Unfortunately I can’t link to their site, because it explains how it works really well. Basically you leave the tollway, pay, turn around with a roundabout and enter the tollway at the exact same place where you left the tollway one little trick that saves you some money.
Check it out, I know it has helped me personally!
