Just to add my experiences. I was able to get one in March last year with the idea to save money on commuting. I commute from Thorpe Bay and buy a daily travel card, using the railcard does save a good few hundred pounds a year against a season ticket. Mainly when you consider my 25 days annual leave, bank holidays and the two week Christmas shutdown at work. This adds up to make my daily tickets much cheaper. As a result when my annual ticket expired in July, it wasn’t renewed. Just to add that I’m one the train now, so don’t have my spreadsheet with all of the numbers.
