Wendy and I recently had occasion to buy two Merseyrail Day Savers, which set us back a total of £11.20.

“Blimey,” we thought, “that’s so much cheaper than the Metro!”

But it’s not. The equivalent Tyne & Wear Metro Day Tickets would have cost us £11.40, and—unlike the Merseyrail ticket—our fare would have additionally covered up to six children. It would have also allowed travel during the morning peak, which the Merseyrail ticket did not. And it would have permitted travel not just on the Metro, but also on local rail services and the Shields Ferry.

It’s funny how perceptions of fares don’t always match reality. Deals can be better (or worse) than they seem.
