When you are ready to checkout, simply add the promotional code into the box in the checkout. If the code is valid, the relevant discount will be applied to your order.
Please note, if you are receiving an error, check the dates of the promotion or the products that it is to be applied to, and the conditions. As our promo codes vary, so do the terms and conditions of each, so make sure you check when you receive any codes. Codes may only be valid for certain items, and most codes will have an expiry date. You should be able to find the terms and conditions in the same place you found the code, whether it be through an email or on our website.
