Good question. We all love discounts!
To use your discount code, please enter it into the "Vouchers" text field on the checkout page. This field is located under the list of products in your shopping cart.
Enter the code and click on the "OK" button. Please make sure the code has been applied PRIOR to completing your payment. If successful, the discount will appear as a line item under your order total summary. Discounts can't be applied once payment has been completed.
