Is there a cutoff date for receiving the following month’s print?

Yes. You need to order before the 20th of the month to receive the next month’s letter. Any time after the 20th and you’ll only recieve your first letter the month following that.

To avoid confusion, look at these examples:

• Charlotte registers on 15 April. This is before the deadline of April 20. She’ll receive her first mail club package in May.
• Eric registers on 22 April. This is after the deadline of April 20. His registration is pushed back by one month. He’ll receive his first Mail Club package in June.
