You can set up a Purchase Pin on each of your cable boxes/DVRs and in the Stream app and web portal.

Thanks for the quick reply, Bruce! If I understand these articles correctly, this is about setting a PIN so a user CAN'T make a purchase without it....but I want to let the user make purchase, but to pay for it themselves. Will this accomplish that?
Thanks again. I was hoping there was a way to make each purchase with a credit card vs. automatically charging the account. Guess I could have them make purchases through a streaming stick instead of through my Comcast account. Appreciate your help!
