If anyone Starts work Monday and usually buys quarterlies 90 days, you will save at least 10 ( depending on distance) If you buy the ticket at your station tonight). Quarterly Valid to Friday 4 April If buy tonight (a week and a half before Easter long weekend). You save more if you buy yearlys, but I think the Opel card will be rolled out by then which should be cheaper overall.
