Hulu offers new members a 1-month trial of its Hulu Plus streaming service for free when you sign up via PayPal. That's the best current offer available for a free Hulu Plus trial; we saw a 2-month trial a month ago. (Without PayPal, the trial period is only a week long.) You must cancel the subscription before the trial is over or you'll be billed for one month of service, which currently costs $7.99.
