Free LA Zoo family pass (but seems to work for other categories also). Good for 1 year admission for you, another adult, and your young kids and grand-kids.
I posted the direct link because the site is slow but you can see get there by going to lazoo.org directly but it takes a few times refreshing to get it to load right now.
Click on membership tab and use promo code 11103NHA.
May take a few tries but I got through.
May be a pricing mistake so don't get your hope up until we find out.
Hope this helps someone.
