You could always try hotwire and see what they offer. It's quick and painless and a good price. I just got 5 days in SLC for $16.95/day = $112 after taxes and charges.
Or you can cut & paste this link and there are a bunch of codes for different organizations:http://www.fatwallet.com/t/63/790643/
It's a bit more work trying out the different codes but you may save a buck or three.
