You can use the Showtime membership to stream Billions and other popular shows.
Brad's Deals Editor Jim,
Get a free seven-day trial of Showtime channel membership on an Amazon Prime account at Amazon. After that, the price returns to $10.99 per month. Cancel your membership at any time. This add-on service works in conjunction with your Prime Video service. With it, you can stream Showtime shows and movies on the same devices where you normally watch movies with Amazon Prime Video. That's the best price we found anywhere for a two-month subscription. Sales tax is charged in most states.
