See for yourself by reading reviews on the most popular resources:
I did not know there was a charge for using this until I got to the very end. I had spent too much time filling out the form to end and start over. I want to cancel at the end of one month.

I thought I was purchasing a one-month subscription (I didn't select the correct button prior to the check-out process and was not advised of the amount before I hit Submit). Would REALLY like a refund of the yearly subscription - am very happy to pay the19.99 for one month. Please...
