I just logged into my Ticketmaster account and I have three separate vouchers for a pair of tickets to....something. Apparently the vouchers are only good as certain events, and there are currently no qualifying events in my city. The vouchers are good til 2020, so hopefully something will show up.
I hate Ticketbastard, but I'll take free tickets.
I think I used them in 2001, but I'm not sure. When I click on "my vouchers" I get a message that says they are experiencing technical difficulties.
In reply to slowride:
I get a message "We are experiencing overwhelming load to our system".
EDIT: I was finally able to get their page to load, and found I have 4-vouchers! For $2.25 each... 
Here is what it says in my "voucher" tab:
UPDATE JUNE 21 1:35 AM EDT In 2003, the Schlesinger v. Ticketmaster class action lawsuit was filed alleging that Ticketmaster failed to fully disclose to consumers all aspects of its UPS and Order Processing Fees. While vigorously defending the lawsuit, Ticketmaster settled the case in 2013, with the court granting final approval of the settlement in February 2015.
The settlement class includes all consumers who transacted on Ticketmaster.com from 1999-2013.
As part of the settlement,
Ticketmaster agreed to provide all members of the class a $2.25 credit on the future purchase of primary tickets for each transaction over the class period, for up to 17 claims.
In addition, a $5 UPS voucher was made available to members of the class who had used UPS delivery during the class period, again to a maximum of 17 claims.
Also Ticketmaster agreed to provide $5 million in ticket vouchers for select Live Nation concerts through May 2017, subject to availability and a cap of 17 claims per account. Given the tremendous initial interest for these tickets, Ticketmaster will increase to $10 million its allotment of tickets made available through May 2017. The potential for additional tickets will be based on the redemption rates of the discount and UPS vouchers.
Checked today, and I have a code for a $2.25 discount, and another code that says "potentially redeemable for 2 tickets to certain LiveNation concert events". Potentially? Currently it looks like I could go to Def Leppard on July 2. There's not too much in my state. I may try to give these away somehow...

Well, that is a letdown. There is nothing on the list of concerts I could "potentially" get a free voucher for that is even remotely close to the driving radius I'd consider reasonable.

Now I'm trying to remember the last concerts I went to, and where I bought any tickets from...
Apparently I have 6 vouchers for $2.25 and 6 vouchers for "redeemable for two General Admission tickets for certain Live Nation concert events ".
Wonder what the chances are for a concert that I have ANY interest in attending?

I've gone through them twice. I doubt my vouchers would be worth the effort, especially if it can only go towards future purchases.
My mom got a couple, the tickets were free, but the usual tacked on fees that double the ticket price were not.
I have been trying to redeem a couple of vouchers for over an hour with no success.
There is a 14 page list of concerts that the vouchers are applicable to. Unfortunately "vouchers sold out for this event" is on EVERY SINGLE SHOW on the list. Like that's not a crock of E36 M3...
So Ticketmaster has many ways to say "berkeley you!"
New news:
Tickmaster has announced it is increasing it's Processing Fee by $2.25....
