Get a Tag Account for Regular Use
If you use the M50 more than once or twice a month, a tag account is the smartest choice. You will pay €2.60 per journey instead of €3.80 as an unregistered user - that is a saving of €1.20 every single trip.
For a daily commuter making two journeys per day, five days a week, that adds up to €624 saved per year. The tag is free when you open an account, and you can manage everything online.
