I have had the Channels Plus subscription in the past. I let it lapse and thought to try it again today. When I clicked reactivate the website said that I would get another free trial and I wouldn't be charged until October 29th. I thought great, wasn't expecting another free trial but awesome, and went ahead with the yearly subscription.
After doing that I was charged immediately. Now it isn't a huge deal but I would think you may want to update the website so it doesn't show a free trial for returning customers and then charge them the full amount without any warning.
I also sent an email to support.
Thanks!
