That’s weird. I’m going to have to investigate this further. I have a couple guesses.
1) It might only be an option to those with BFF status, so it’s showing to me but not you and I assumed it was available to everyone.
2) It’s only available on the app, which would be a weird choice.
3) Book of the Month hates you.

I did it last month, so I know it’s possible. I’ll have to contact them and see what I’m missing here.

Thanks. I only see the skip month box. Maybe it is because I am new but I contacted BOTM. Thank you!

Underneath the December books, there’s a link that says something about choosing another book. It’s not glaringly obvious, but it is there in the same spot where you can choose to skip the entire month. I’d tell you exactly what it says, but I already ordered my December box, so it doesn’t show me those options anymore.
