The real damages here are going to be to the banks and credit card companies that will have to absorb the costs of all the fraud.
As to the Ticket Master case, you can read the complaint yourself and see if $5 or so per class member settlement value was reasonable: http://www.ticketfeelitigation.com/docs/Fourth_Amended_Compl.... The theory was that TicketMaster didn't disclose that it was marking up fees for things like UPS delivery and order processing, and that if customers had known they wouldn't have ordered the tickets. That's a weak damages theory, because customers don't care about line items they care about the bottom line. Either they'll pay $X for the tickets or they won't. Unsurprisingly, that weak damages theory lead to a small per-class-member settlement.
