If you sign up in-between two seasons, you will get the seasonal box that is currently shipping. You will see the season displayed when you choose which box to subscribe to as well as in your email confirmation.
If the current seasons box is sold out, you will be automatically enrolled for next seasons box. You will receive that once shipping for that season has begun. Check out shipping schedule if you have any questions.
Please been aware that if you sign up towards the end of the season, you will be receiving your next seasons box shortly after.
