We are a monthly subscription. That means you are re-billed every month. When you purchase your first box, your card is charged immediately (that same day). Re-billing for future boxes always occurs after you receive your box. You will be re-billed on the 15th of each month.
Boxes are shipped out the first week of each month. To receive the "current" box, you must sign up on or before the last day of the previous month. For example, in order to get the "October's box", you must sign up before the last day in September.
