Edit: As mentioned below, use the KOTC promotion. Note with KOTC ... if offered, it is a SEPARATE promotion box (which actually says KOTC next to it). You can get the $95 seats for $60. At the box office, you have to buy four tickets when using this promotion, but with Ticketmaster Online, you should be able to buy alternate quantities.
All other discounts appear to be dead (but you can always try 5WINTER, 6WINTER, and 7WINTER ... I've seen them all).
End of edit.
EDIT: As TAF mentions below ... use 5WINTER to get actually 50% off! (Just received a new email with this discount ... it is for those who have previously seen Wicked ... but there does not actually seem to be anywhere to track it, so it should work for anyone.) End of edit.
Enjoy Wicked on a weeknight in January and February with a 50 percent discount on orchestra seats by entering code 7WINTER.* (See below ... at this point with Ticketmaster, the discount is more like 40%.)
Tickets at 213-365-3500 or online at www.Ticketmaster.com. For more information and ticket availability, go to www.wickedthemusical.com/la.
*Offer is good for performances Tuesday - Friday from January 8 - February 29. Subject to availability. Not valid on February 14.
Orchestra Seats were usually $98, and are listed as this on the official site and the Pantages site. But with Ticketmaster, it looks like ticket prices have dropped to $95.50 (for standard full price). And Ticketmaster is actually not giving 50% off (as per the deal) ... the tickets are coming up as $57.50. But you can get some decent seats (say around row R or farther back, just left or right of center).
The discount is, of course, off of the base price. You will add building charges, convenience charges, and order charges with Ticketmaster. I was able to use the last code (FAMILY, for the KOTC promotion) at the actual Pantages Box Office and get the deal without paying Ticketmaster charges (I did have to buy 4 tickets, though), but YMMV.
