Billing will occur on the 9th of each month. If you sign up prior to the 9th, you will be billed nothing initially, charged on the 9th of that month, and you will receive that month’s kit. If you signup after the 9th of the month, you will not be billed until the 9th of the following month, and the first kit you receive will be next month’s kit. If past kits are being purchased, credit cards are charged immediately and shipping occurs shortly thereafter.
