Your coupon voucher is usually a code of letters and numbers which will be sent to you by email. Most coupons are valid for 3 months. When placing an order, please input the coupon code into the ‘Coupon’ box, at the bottom of the checkout page, and select “Use Coupon”. We will automatically show you how much your order costs before using the coupon and how much you’re expected to pay after this discount. Once that’s done you can proceed to checkout.
