Applying for a discount code is pretty simple. When you click 'Add to truck' on the item you need, you'll be taken straightforwardly to the checkout page. On the correct side of the screen under the total price, you will see a line saying '+Apply gift voucher or code.' Click on that line. It will change into a text box that reads, 'Enter code.' That's the place where you have to type in your code. At that point, hit the 'Apply' button to the right end of the content box to apply the code.
