Go to www.mousesavers.com
Go to non-Disney Theme parks and attractions
Go to Sea World Orlando
Look down for the Wendy's COMBO offer - $10 off each ticket.
There is a AAA offer from AAA South but when you start to follow it through it looked to me like you had to live in FL (or somewhere down there) to get the tickets.
Hope this helps !
I did my homework everywhere and the best price I got for one day at SW was through AAA.com all you do is print it right on your computer so no need to worry about the mail or picking it up.
