Birchboxes are only available as monthly, 6 month or yearly recurring subscriptions. If you would only like 1 box, you are able to cancel your monthly subscription any time before your monthly billing date, which will always fall on the 1st of the month. If you cancel your subscription - this will not stop the first box on the subscription from shipping. If you have already been charged, your cancellation will be effective for the following billing cycle and you will still receive a box for that month.
