Were can i get free Amusement park tickets online?

I really want to go to Carowinds Amusement Park in Charlotte, North Carolina. But the tickets for each person are about $50. and i cant afford that. Does Anyone know a Website that i ca actually get tickets for free? and id rather not have a website that requires me to make a subscription to anything, or enter personal information, or gives my computer viruses. if anyone knows a website, please tell me!
