Simply visit a full-size or travel-size product page and select "Autoship and never run out." Choose your delivery frequency (1-6 months) and add the item to your cart. Repeat with other products you'd like to add to your subscription, or as a one-time purchase. Complete checkout and receive 10% off all items in your autoship subscription, plus free standard US shipping.
Please note: one-time purchases can be added to the first order in an autoship subscription but not to an existing subscription.
