Damn. Looks like either they forgot to send them. I spoke to someone st the third party company who deal with ticketing and they thought they had only dispatched one item to my fan number. That must be the away ticket. Hopefully they can email me a print at home on Monday
Did they arrive in the post together? I ordered both on Monday, got my away ticket on Tuesday and assumed that they were prioritising the despatch, but I got home from Sheffield this afternoon and realised the tickets for this Monday still aren't here.
