For customers who purchased tickets through Ticketmaster between 1999 and 2013, it's time to check into that account again. According to Gawker, Ticketmaster has begun to pay out a $400 million class action lawsuit through discounts and vouchers for free tickets. The ruling applies to about 50 million ticket buyers. To check on the free tickets, log into the Ticketmaster site and then click on "Active Vouchers" to redeem tickets from a list of eligible events. There could be some free shows in your future.
