Can I change my order details after it has been placed?
Unfortunately, as we work so quickly to send out your order it is very difficult for us to change details after an order has been placed. If you contact us within 15 minutes of placing your order we can usually make any changes required. After this point, we can't promise we will be able to, but don't hesitate to contact our support team using the details below who will do all they can to help you.
Can I use more than one discount code on a single order?
Only 1 discount code can be used per order. If more than 1 code is applied the the code offering the larger discount will usually take priority but it is the responsibility of the customer to ensure the correct code is used.
Can I use my discount code on products that are on special offer?
Discount codes do not apply to products that are on special offer.
