We send you an email reminder 10 days before each order is placed in case you want to make any updates. Changes to orders can be made up to 24 hours prior to the next scheduled order date. Then, we will place your auto-replenish orders automatically for you, based on the frequency you set for each product. When your order is placed and then shipped, you will receive emails from us letting you know, just like you do for an order you place yourself on livingproof.com. You will only be billed when the order is shipped.
