ticketbastard class action settlement
Ticketmaster just settled a class action suit for being the douchebags they are. If you've bought tix through them between 1999 and 2013 you may have some vouchers on your account. I had a shit load of them and in classic Ticketbastard fashion they're harder to use than airline miles.
You can only get GA tix from an approved list of shows, wasn't a lot to choose from in my area. I got four tix to Prophets of Rage, Black Sabbath was sold out.
If you don't have codes but see a show on the list you could use tix for hit me up, I've got codes for about a dozen pairs.
