If you have a coupon code / discount code, there is an option to add it at checkout prior to the payment page.
Any discount or promotion will be visible once your coupon code has been applied successfully.
In many cases, if you have a coupon applied to your account it will automatically be populated when you visit the checkout.
If your coupon isn't working, no dramas... we'll get it sorted!
First, please double check you have copied it correctly, and that the coupon / discount has not expired.
If you are still having problems, please contact us using the "Contact Us" link in the top right-hand corner of this page and we'll investigate for you.
