How to get the birth control pill for cheap?

I just recently turned 18 and would like to get on the birth control pill without my parents knowing. However, I am still on my parent's insurance and would not be able to use insurance to lower the cost of the pill without my parents finding out. I also do not have a job because I play a year-round sport that I am going to college for. I have already called my local planned parenthood and they said I would have to pay $60 because I have no insurance and $25 each month for the pill. Is there anyway I can get the pill cheaper?
