Promotion.

I forgot to enter the promo code which I received in my email during my order, to get a $100 gift card, can I still get it, or did I lose it since I forgot to enter it?

i tried the chat help, but they told me to call the 1800 number. I called the 1800 number and they told me to go to the physical store. At this point I am extremly frustrated, Is there anybody that can help me.
