Just wanted to let others out there know the issues with opting out on this website!
I posted an ad in January and clicked on and pay for the 'month' fee. They've since taken money from my cc in February, without me knowing they were going to do this. The shocker is that you can't cancel an account online - even though this is how you set it up. The only way to stop them is to call, then send and email, then they'll cancel your account.
Just a warning to others that they'll keep charging you unless you end them a specific email
