If you checked out as a guest, and therefore don't have an account, you can track your order by waiting for your dispatch email.
When you place an order with us, you receive two emails. The first is an order confirmation (if you don't recieve this straight away don't panic as this can take up to 1 working day), the second is the dispatch confirmation. On this second email is the link you need to track your order on the couriers site. Please note - you will need to click on this after 7.00pm on the day of getting your despatch email as it takes a little while for the information to be updated.
