I Need Help With Gamefly?



I am wanting to become a member of Gamefly or Gamerang. But under terms of use it says you have to be 18. Im 17 and have my own checking account and debit card. I know that if I ask my parent if I can become a member to this site, she is going to make me pay for it. So do you know if I can just become a member by myself, or will it make me add my mom or dads credit card to the account also, if its going to make me do that, then i wont be able to get the service.

If anybody knows, an answer would be greatly appreciated,

Thank you,
If i lied and just set it up myself, would could happen? and are the chances of the finding out high? If i use my debit card, wouldn’t they be able to see that I am not 18 through that?
