I bought the software today and so far am really impressed with all the amazing features. I have a recurring subscription for $16.95 but i have a 7 day free trial. I use authorize.net AIM. One thing that I haven't been able to figure out is how to verify the users credit card info when the amount is 0 (maybe transaction type should be set to auth_only?) I just don't want the automatic payment to fail when the users free trial ends. Thank you for your great product!
