Already have a discount or coupon code that you want to use? Here is how.
Add your desired items to your cart. Review the contents of your cart, check the Terms and Conditions box and then hit, "Proceed to Checkout."
You'll be taken to the check out page. On the right hand side you'll find a box that asks you for a "Gift card or discount code." Enter your code and hit "Apply."
The discount code will be applied to your order and you can check out like you normally would.
