Once you have paid for your order you should receive an email confirmation from Worldpay to confirm your payment receipt. This then sends a confirmation to Shopify, my website host, who then generate an order and automatically email you the order confirmation with your order number. It is really important you input your correct email so that you get the confirmation email as I will also send updates and tracking numbers to this same email address.
If you did not get either of these emails please check your junk/spam folder. In the unlikely event that you still cannot find one or both of these emails then please contact me and I would be happy to send your order confirmation manually to you, or update your email address.
