Have any of you bought concert tickets off Ebay? This one girl has 2 tickets, and the seats are GREAT. Bid is currently $30 cheaper than what I could pay for them at TicketMaster, were they still available to buy. Problem is, despite the fact that this seller has 9 negatives (mostly miscommunication) out of over 980 in total feedback, I'm nervous to even bid! How do I know I'm actually buying tickets??
