Christmas Sale Discount Code "XM40" Isn't Working

(sorry there doesn’t appear to be a proper category to select)

Hi Arylic Team,
I’m attempting to purchase a Up2Stream Amp 2.1 using the Discount code: “XM40”. The Checkout page returns, “Enter a valid discount code or gift card”.

The last email reminder I received stated, “Last 24 Hours to Get Up to 50% OFF :christmas_tree:” and that was ~17hrs ago.

What should I do to use the code?
