Payment information is required to start the 30-day free trial.
You will not be billed for the first 30 days of service, however you will need to cancel your service (by contacting support@choicebot.com) prior to the end of the 30-day free trial if you wish to avoid payments thereafter.
Please note that only PayPal is supported at the moment. Credit card processing is being added, and will be available shortly. Sorry for any inconvenience this may cause.
