they also charge for postage now
I stopped using thetrainline when they also started charging for the postage to send you your tickets. Now use the FGW site which doesn't, nor for using credit cards. However it suffers from the same problem as ttl where you have to go through about 5 screens confirming the same details for each ticket you buy (eg. yes, I still understand the terms and conditions; no, I haven't changed address since adding the previous ticket to my basket etc.) when buying more than one. Also haven't found a quick way yet of getting to the screen where you can select from your 'favourite journeys', which is easy in ttl.
