Let us know as soon as you can! If you have just placed an order and realise immediately that you need to cancel or amend it we can usually accommodate your request. However, if we have already despatched your order we will not be able to help you until the goods have been returned to us. Note that refunds are usually batch processed at the end of each week and that it can take a few days for any refund due to your credit or debit card to appear in your card account.
