Thanks for your question. Every Huel customer is able to create an account on our website using the email address they used when placing their initial order.
For our subscribers, you can log into your account to view your upcoming shipment, or cancel that shipment if for any reason you wish to make a change or no longer receive Huel.
We are working to add more options like pause, modify, and restart, and hope to have those added to the functionality soon.
As far as deadlines, if you wish to cancel an order, you simply need to do so by the day before your next subscription order date. There are no penalties for cancellation, and you can start a new subscription at any time.
There are no fees for having a subscription; you actually save 10% just by placing a subscription order.
