In case you enter a discount code during checkout that doesn't exist or isn't currently active, then you can see the message: “Unable to find a valid discount matching the code entered”.

Of course not, most coupons may be used only by you when you received them directly from Una Doua. As the Una Doua coupon includes your User ID, it cannot be resold or transferred in any way.

Normally, one discount code is only applied for one offer. However, If the users put a vast of items in their cart, it is easy to use one coupon code to purchase items. It depends on Una Doua's policy, you can contact Una Doua via mail for your reference.
