All orders are one-time purchase. This means that you won't be "locked" in to a monthly subscription. Rest assured that you don't need to commit to a monthly subscription unless you choose to. There are no recurring or hidden charges at all.
For customers who are interested in getting onto a subscription plan, so you don't have to keep re-ordering monthly, we have a separate Autoship page for you to shop from.
Otherwise, all orders are one-time purchases.
