This is my case as well. No code.I signed up for the $19.99/yr special on Peacock last year. Today I went into my account and discovered that the $59/yr cost was crossed out and the $19/yr was being offered for my renewal rate. It doesn't appear that I have to enter any code or do anything other than allow the charge to go through on my credit card on 9/7/2023.
I checked google and Peacock doesn't show this special rate so maybe it is only being offered to people who are already customers
I had signed in to cancel as it expires 9/4. Thinking I would renew monthly for Skate America. Nice surprise and hope Peacock dies have skating this season. Thxs
