You can buy a $26 voucher for $13 that is good for two tickets at many theaters. Go to www.hollywoodmoviemoney.com
and enter promo code 38741 and then your zip code to first see if theaters accept it in your area. I've used Hollywood Movie Money before with no problems. Note, this goes directly to the theater, so you also avoid the Fandango fees.
This is at Geico privileges, but the sign up is free and I don't think you have to use Geico.
Update: So, you do have to actually pick a theater before printing the voucher (not the date or showtime, though). You have to purchase 2 tickets at one time. And, this voucher expires on 6/30/2012. Not as great, but still OK deal.
