Hi Brian,
Yes you can configure the Payment Registration Pro module to offer a 2 week free Subscription with a 1 Month Subscription. Trial options can be configured on the Product Setup screen. Please note, Trial options are currently only available when using Authorize.net or Eway as your Payment Gateway. More info about the Trial Subscription Setup can be found in the Product Setup KB article located at the following link:
