Be careful with automatic renewal. On the day they charged my credit card for an automatic renewal I wrote to cancel my subscription. They didn't. Instead they wrote back to say my subscription would end a year from that date. I called Parallels support and in a long call they finally said a refund would be issued. When I received credit card refund it was for %75 of what I had been charged! What a quibble. That's not what I expected nor do I feel that I was treated fairly. Be careful dealing with these people. They don't seem to act in good faith. It may not be wise to subscribe.
