What plan are you currently on? If it's more than $35, you likely won't see this option. A workaround is to renew into the $30 plan now, which will unlock the $35 plan that you can then schedule a change to it at next renewal. Just know that you won't get any credit/refund for unused time in your current cycle if you renew now into the $30 plan, but if you wait that deal will likely be gone on January 1st.
