(apart from needing to win this one first) that would depend ENTIRELY on the 'status' of the opposition.
'Unglamorous' - basically anyone outside the top 6-8 in the PL, then I'd imagine pricing would be similar - perhaps a fiver more for a West ham, Everton, etc.
'Glamour' tie - City, United...
Went to buy 'my seats' yesterday, in E1C, but had missed the boat.
Would quite like to try ESU but bottled it and bought in E1B as didn't want to risk being stuck in some crappy front row seats, in the unlikely event that they don't open a top tier.
