What if I want to return part of an order that came with a voucher? Hiren Parmer May 14, 2018 10:24 Follow Whether you return your order partially or fully, your voucher will be cancelled. You will however, receive a refund for your return. If you've already spent your voucher, the value of the voucher will be deducted from your refund.
