If your discount code is not working please email us at customerservice@magneticmobility.ie before placing your order. We cannot add the discount code to orders already placed. If you do not see a box to enter the discount code at the checkout, hit the back button on your browser and apply it in the Shopping Cart. Please note that some discounts may be automatically applied if you clicked a link on an email from us. In these cases, there will be no discount box visible, however you will see a note on your checkout page where the discount has been applied.
