How to Apply Promo Code
When viewing your cart (check out page), enter your code in the "Please leave special instructions" text box under "Order Summary section" (see image below).
Note: only one code can be applied at a time. If you'd like to replace a code, simply go back and enter the new code in the text box.
You can also enter your promo code on the final check out page under "Discount" and click "Apply". (see image below).
