Busch Garden Discounts-Pop can discounts? Where should we get our tickets?

[IowaGirl]

Hey everyone-- I am hoping someone will read this who lives near the Tampa area..
We have one day for Busch Gardens in Tampa, August 6. How should we get our tickets??
Six Flags around here advertises on coke cans a ten dollar discount if you bring in a can. You can even get free kids tickets from buying Danimals kids yogurt for Six Flags.

Anybody know of discounts like that for BG? Or any other applicable discount??

Thanks!
