Just seen this advertised on a website, basically if you download the free arriva app, they are offering a free day saver ticket between the dates in the title. You need to enter code 4343. I just done it then, really simple and they send you a confirmation text too with your activation code. Can't go wrong really, think they are about £3.60 where I live. It all helps. Link should take you straight through to site with more info on.
