My mistake, I'm using "gmthanks20", if you see a typo there let me know, as I really do want to the discount, but it did initially work, then I added another product to my cart and it stopped working. So I'm assuming a bug and not a typo.
Let me know what the order number is that you want to apply the code on. While the code is expired now, i can see that your request came in before the expiration and would be happy to help out with that.
