InstantProfitz is a site that pays you to sign up for offers, most of which are completely free. You don't need to have a credit card or pay a cent to make money on this site. They pay you when you reach $20, which is quite easy to obtain when most free offers are worth $0.50 to $1 each, and there are multiple pages of offers.
You can request payment by check or Paypal.
Here is proof of my payment of over $60 from earlier this year:
