Longshot request for the O2 tonight...

Hello, I know this is going to sound like a scam but I promise it isn't! I went to the Mumford and sons show at the O2 last night I wanted to get one of the limited edition prints from the merchandise shop but when I went after the concert it had sold at the days allocation. I know this sounds weird but I was wondering if anyone could help me out if you were thinking of buying some merch and could pick one up?

Like I said I know this sounds weird but I'd be happy to send the money before the show and then some postage as well later? Worst case scenario for me is I'm out £30 and you're up £30 if you decide to keep it!
