I just checked what I'm owed on the Ticketmaster class action at https://www.ticketmaster.com/member/vouchers, and I'm getting 17 free pairs of tickets to Ticketmaster and Live Nation events. I'm also getting 17 vouchers for $2.25 discounts, which I'm not quite as excited about. Apparently I maxed out; 17 pairs of free tickets is the maximum allowed per person under the settlement.
They haven't yet posted any eligible events yet. I'll bet they won't be offered on any events that are close to selling out, and they are for the cheapest seats in the house. I have to use them within about four years, which shouldn't be an issue.
