The Raspberry Pi Zero is incredibly popular, and as a result, we tend to sell out very quickly! As an official reseller, we are only authorised to sell one board per customer.
The boards are produced by Raspberry Pi and they can only make so many, so we're at the mercy of the busy production line!
We don't usually know when more will be available, so the best chance of getting your hands on one is to register for email notifications. Click the 'Notify Me' link on the Raspberry Pi Zero product page and we'll email you the second it's back in stock.
Note: Please do not raise a support ticket related to Pi Zero stock or ordering more than one board - our support team cannot provide any information on incoming stock.
