They reciprocate with some other zoos. For example if you're a member of Oakland Zoo or Happy Hallow, you get half off tickets to SF Zoo.
They have a few free days for sf residents and for the public on other days. Best to check the site. Also living social has discount tickets sometimes
My ticket was $19 (I think it might have been part of a limited time offer) but I know there were discounts for residents and more
