Some great code, but should be looking much nicer ;)
(BTW: the 2 printout is intended to be different? If they should be the same, than the first function could call the secound within the first condition, thus leaving less space for making any mistake editing only one of them if needed...)

Doesn't seem to work with latest Woocommerce since $order->get_used_coupons() will never return anything.

Great code, really helped me out, but i also added one line of code to show the amount of the coupon used:
echo $order->get_discount_to_display();
I added it right after the "foreach" function

how to send the coupon descritiption to the customer for order mail, can anyone help me on this it is urgent

Is there a way to show the amount of the coupon that was used? Currently using the code below and i want the amount of the coupon to be displayed as well. We use multiple coupons and want the amount for each to be displayed
