JIt costs $99 p.year ($9 pm), and automatically credits your card each month/year. I have found many have difficulty getting out of these types of sales.
If it's an option, use PayPal on this type of thing. You may not be able to get out the first year, but many of those companies continue to bill you year after year. It's sometimes difficult to get your credit card company to undo those deals. (You were supposed to notify the seller 10 days before the billing cycle or you have to notify them in writing, or you have to telephone them and no one ever answers the phone, you don't find out that you've been charged until 2 months later and they don't issue refunds, etc.)
Paypal doesn't give you any grief. They just refund your money right away. Also, Paypal notifies you by email when a charge is placed on one of your cards through them. So, you can handle it before it's two months old.
