How does the refund work where I have used part Gift Card or SilkFred Store Credit to pay and I only want to return part of my order?

If you purchase more than one product using a combination of a gift card or credit voucher and card payment, the gift card or credit voucher is applied across all products in your order. It works so that the same portion of each product is paid for by the gift voucher or credit voucher, with the remainder being paid for by the card payment. If you then request a refund for part of your order, you will receive the relevant portion back to your gift card or credit voucher and to the card that you paid with.
