Here's how it works:
1) Go to our Sign Up page.
2) Select the edition you are interested in and choose a "monthly subscription" plan.
3) Your first month will be absolutely free! Your card will be pre-authorized (but not actually charged) for the amount of $1 for security purposes. The authorization will automatically disappear within 7 to 14 days. In 30 days, your card will be charged for the plan amount and will contnue to be billed monthly until you cancel.
