Where do I enter a discount code?

If you have a discount code here's how you enter it. Starting on your cart page, you first have to hit the red checkout button. Then you get to the first page of checkout as shown below. In the order summary box on the right (it will be in a different place on some mobile devices) you'll see "Gift Card or Discount Code." That's where you enter the code and hit APPLY and it will then deduct the code's value from your order.
