The Phoenix book seemed to go through a few lean years, but most recent ones have been pretty good. I've used attraction coupons too. For 2007:

Scottsdale Center for the Arts concert ticket: $48
OK Corral Stables horseback ride: $30
Desert Botanical Gardens: $10
Boyce Thompson Arboretum: $7.50

I've also used at least $100 worth of restaurant coupons.
