So I have a 3 month internship in Battersea, going to Clapham common underground station Monday to Friday, getting the 7.38 train from St Albans. Whats my cheapest option, I'm getting very confused, I am also likely to spend some weekends in London/stay there on a Friday night etc so will potentially be buying tickets for sat etc, but not always. I also have a 16-25 railcard, so not sure if this complicates things A day travel ticket from St Albans with my railcard is £11.55 (a price i think you can only get at the station). So essentially I'm confused at whether to buy single daily tickets or a monthly pass. I'm assuming i'll need to buy the monthly travel card but just thought id check there wasn't a cheaper way! Thank you!
