Why is a promotion code not working?
Derby House promotional codes often run for a limited period of time so please make sure you check the expiry date of the code. They do not apply on certain brands, discounted items and hardware unless otherwise specified. We are unable to apply a discount after an order has been submitted.
Only one promotional code can be used per order, and we are unable to combine promotional codes together. We recommend that you use the code that gives you the best deal.
If the item you are trying to purchase is showing the promo box next to the image but after adding the promo code at the checkout stage the discount has not applied then contact us with the product code of the item(s) you are trying to purchase so that we can check for you.
