I just checked my App.
The 59.99 is annual for just Paramount, no Showtime, with ads.
Ad free includes Showtime and is 119.99 annual, which works out to 9.99/month.
I didn't see a 29.99 option.
I'm currently paying 11.99/month for ad free +Showtime.
I downloaded the app and it had an option for a 30-day free trial. It never asked me for a code.
If i dont get through Picard, Scorpion and Man with a Plan by the end of the month ill try the codes. Worst case scenario ill pay for a month if i need to. But i cant see myself keeping a monthly...
