When you first sign up for a subscription, your first payment will be charged at the time of purchase. In the months following, payment for your future orders will be processed based on your selected frequency (every X month(s)/weeks/days). Sometimes, we may adjust the date to combine your subscriptions if you have more than one upcoming charge within a few days of each other. We do this to help save you that extra shipping charge!  The Upcoming Charge Date email is sent 3 days before your order is billed.
