Yep we have done the same. Be careful though, I heard from a mate last night who had done the same and hadn't received his tickets. He rang the Fulham TO to be told that they had cancelled them because he had a Dorset Postcode.
My lad has just called me to inform he and the youngster can't go, so have an adult and under 16 (or whatever age the concession was at) available. I'll be going so can meet at the ground,
