Passengers in Essex are being given the chance to try the bus at a reduced fare as part of Catch the Bus Week 2014.
They will be able to benefit from 20 per cent off the First All Essex Weekly ticket, on any First Essex service.
Tickets must be purchased on board the bus.
Led by Greener Journeys, Catch the Bus Week is an annual, nationwide campaign to encourage fewer car journeys and more trips by bus and coach.
The initiative runs from Monday April 28 to Sunday May 4.
