Unfortunately, a voucher can only be used only once on our website. These unique coupons codes are deemed as “redeemed” once the order is placed.
If you have placed an order for a different size or for a lesser quantity than the voucher entitles you to, there will be no possibility of making changes to any of the orders already placed. However, please contact us with your order number and voucher code, and we can assist you to place an order for any value of your deal you have missed out on. A separate delivery charge will be applicable. You can email us here (https://pix.zendesk.com/hc/en-us/requests/new)
Thank you for your understanding.
