DON'T do it. It looks as though you are buying a link to another website where you can buy tickets. It all looks a bit dodgy to me. Unfortunatley, E-Bay attracts people that play on genuine fans like us being prepared to pay higher than the odds for tickets, and end up laughing to the bank.
That's obviously just my opinion, and if someone wants to give it a go, that's up to them....I must be getting sensible in my old age...
