Phoned yesterday CCS. Asked them if they could find tickets for next Saturday's quarter-final match (Brazil World Cup), since FIFA's site had them all sold out. The girl who answered said that they actually could find the tickets, and that she would email me the prices shortly.
I got the email an hour later. $2800 per ticket on the cheapest location. lol. FIFA's site sold them starting at $250. Total rip off.. I've only had great experiences with Amex Concierge .. but I just can't believe they are re-selling tickets to me this way..
