After the cart page, once you check the "I understand" box, you'll be directed to a page where you add your billing and shipping information.
On a desktop, the place where you add your discount code is to the right, in the blush box.
On mobile or a tablet, the space for the discount code will appear at the top of the screen (see image on left). Once you click the cart to expand, there will be a space to enter your discount code (see image on the right).
Enter the discount code in the space provided, click the arrow, and you're all set!
