Instructions:If there are any students out there like myself that rely on the Arriva bus service then this may be useful. Just used it now and it reduced my ticket from £249 to £211 in Liverpool.
When you go to the Arriva Bus site for students, select your area and then press buy ticket. A popup window should appear and on the left a promotion box will be available for you to enter the code.
It also enters you into a prize draw to win a 1GB pen drive :D
