I turned off the auto renew (canceled) my subscription, why did I receive a box this month?

If you turned off your auto renew (cancel) your monthly subscription after the 8th of the month, you would still receive a box for that current month. However, if you turn off your auto renew on or before the 8th of the month, you will not receive a box for that current month.  

Additionally, if you turn off the auto renew from your prepaid plan before you have received all of your prepaid boxes, you would receive boxes until all of the boxes have been delivered.
