You can skip the next order from your account. 

Once signed in please click on 'Subscription' tab, you can also access your subscriptions by clicking 'Manage Subscriptions' : 

I wish to skip my entire order:

You should be able to see your all upcoming orders within your subscription dashboard - click on the order that you wish to skip and choose how long you would like to skip this order for. Alternatively, you can gift that month's shipment to a friend or family member. 

You should then see the updated delivery date appear. 

I want to skip part of my subscription, but not all of the items:

If you have multiple items in a same subscription, and only wish to skip one of these, you will need to click 'Edit' on the item within the subscription, and then skip the item(s) you do not wish to receive. Please be sure to click on 'save changes'.
