All customers who have placed an out of stock request for a particular item will be notified when the item comes back in stock. Sometimes we only receive one item back via our returns or a small order meaning that if you don't get in quick, you may miss out.
There's always a chance that more stock may become available again in the future so we recommend adding yourself back onto the out of stock request list if you miss out the first time. You can do this by clicking on the 'resubmit request' button at the bottom of your back in stock email. Fingers crossed for next time!
