It's very annoying that East coast will no longer post tickets in normal post.
You only get a first class (£1) option if (I think) you are booking more than a week in advance. You can't get it if you are changing a ticket, you are forced into taking a £5 hit for special delivery for that, or going to the station to make the transaction. You can't even pick up the rescheduled ticket from the machine.
I wonder what happens if you arrive at Waverley 15 minutes before due to depart and the fastticket machines are down. I've heard of people getting rough treatment from EC guards due to lost tickets or machines not printing tickets, even when they have proof of purchase of ticket, email of reservations printed out etc.
EC have a "print your own" facility for some tickets, but then you need to carry your birth certificate, NI card, blod type, mother's maiden name, name of first pet etc. to prove it is your reservation.
I would like a proper digital ticket I could have on my phone.
