Although its not disastrous ($5 loss) don't assume the auto renew OFF is OK. It means they will take the funds if they are in your wallet but won't take from a card. I searched high and low on the site and can't see the option to not touch your wallet. It even says I have no subscriptions.
So in 3 months I will have to top up the $50.00 and purchase the year sub before they take the 3 months again.
