FREE Hershey Park Tickets when you buy Pepsi

I just wanted to make sure that you didn't miss THIS post from MomsNeedToKnow about how to get Hershey Park tickets for FREE. It's a decent deal. Not a great deal. And I don't know if I've see the tearpad forms that she's talking about in the post. Let us know if you find them. Do you go to Hershey Park in the summer?? If so, how do you keep it affordable??? From $10 parking to $15 locker fees....it all adds up so quickly!
