A:Answer If you are referring to to the DirectTV now app through the Amazon firestick I can answer your question.
Upon signing up for the free trial, you will be prompted to put in credit card information. I do believe there was like a $1.00 withdrawl from your account, then it was placed back in. You can easily cancel your free trial anytime before the date it tells you that the trial is over. If you do not cancel, your card will be charged according to the option of channels you choose when intially setting up the free trial. For example, I chose the least amount of channels, so each month I am charged a little over $36.00 including the tax. Hope this answers your question!
