Police Fire and Military get a discount
If you have AAA, go to a local Cincy Office and buy your tickets there as the AAA discount is a little better than the zoos online discount (my apologies as I don't remember the exact discount just remember it was better than the online zoo discount).
If you receive Food stamps, you can get a reduced rate family pass at Guest Services
If you get your tickets online it is $68 but if you buy then at the gate it is $72
$17 if purchased online $19 at the gate for adults. $12 online and $13 at the gate. You might want to check the website for deals.
